+# Support
+
+This repository is focused on bugs and issues. We unfortunately can't answer all support questions in a timely manner. Our software is free and open source, meaning that the use of our software is optional.
+We hold no liability and there is no obligation to support. We will provide support on a best effort basis.
+
+If you use the software commercially and need elaborate support or need it urgently, we can offer this on a commercial basis. 
+Please contact info@spartner.nl or via phone +31 (0)10 744 9312 or visit the dedicated page with more information:
+
+https://laravel-excel.com/commercial-support
+
+Also note that we are a wrapper package around PhpSpreadsheet and thus we cannot answer all questions that are about PhpSpreadsheet functionality. You could ask your question on Stackoverflow or a Laravel-related forum:
+
+- https://stackoverflow.com/questions/tagged/laravel-excel

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at patrick@spartner.nl. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution

-GNU LESSER GENERAL PUBLIC LICENSE
-
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.

-To publish the config settings in Laravel 5 use:
+**Spartner**
+Markt 2
+6231 LS Meerssen
+The Netherlands.
 
-```php
-php artisan vendor:publish
-```
+More about the license can be found at: [https://docs.laravel-excel.com/3.1/getting-started/license.html](https://docs.laravel-excel.com/3.1/getting-started/license.html)
 
-This will add an `excel.php` config file to your config folder.

-# Styling sheets
-
-### General styling
-
-If you want to change the general styling of your sheet (not cell or range specific), you can use the `->setStyle()` method or any of the other setters which can be found inside the export documentation.
-
-    // Font family
-    $sheet->setFontFamily('Comic Sans MS');
-
-    // Set font with ->setStyle()`
-    $sheet->setStyle(array(
-        'font' => array(
-            'name'      =>  'Calibri',
-            'size'      =>  12,
-            'bold'      =>  true
-        )
-    ));
-
-### Styling with PHPExcel methods
-
-It's possible to style the sheets and specific cells with help of PHPExcel methods. This package includes a lot of shortcuts (see export documentation), but also always the use of the native methods.
-
-    // Set background color for a specific cell
-    $sheet->getStyle('A1')->applyFromArray(array(
-        'fill' => array(
-            'type'  => PHPExcel_Style_Fill::FILL_SOLID,
-            'color' => array('rgb' => 'FF0000')
-        )
-    ));
-
-### Using HTML tags
-
-Most of the HTML tags are supported.
-
-    <html>
-
-        <!-- Headings -->
-        <td><h1>Big title</h1></td>
-
-        <!--  Bold -->
-        <td><b>Bold cell</b></td>
-        <td><strong>Bold cell</strong></td>
-
-        <!-- Italic -->
-        <td><i>Italic cell</i></td>
-
-        <!-- Images -->
-        <td><img src="http://github.com/img.jpg" /></td>
-
-    </html>
-
-> Inside the `view.php` config you can change how these tags will be interpreted by Excel by default.
-
-### Using HTML attributes
-
-Some of the basic styling can be done with HTML attributes.
-
-    <html>
-
-        <!-- Horizontal alignment -->
-        <td align="right">Big title</td>
-
-        <!--  Vertical alignment -->
-        <td valign="middle">Bold cell</td>
-
-        <!-- Rowspan -->
-        <td rowspan="3">Bold cell</td>
-
-        <!-- Colspan -->
-        <td colspan="6">Italic cell</td>
-
-        <!-- Width -->
-        <td width="100">Cell with width of 100</td>
-
-        <!-- Height -->
-        <td height="100">Cell with height of 100</td>
-
-    </html>
-
-### Styling through inline-styles
-
-It's possible to use inline styles inside your view files. Most of the general styles are supported.
-
-    <html>
-
-        <!-- Cell with black background -->
-        <td style="background-color: #000000;">Cell</td>
-
-    </html>
-
-> Inside the reference guide you can find a list of supported styles.
-
-### Styling through external CSS file
-
-Styling can be done through an external CSS file.
-
-External css file:
-
-    #cell {
-        background-color: #000000;
-        color: #ffffff;
-    }
-
-    .cell {
-        background-color: #000000;
-        color: #ffffff;
-    }
-
-    tr td {
-        background-color: #ffffff;
-    }
-
-    tr > td {
-        border-bottom: 1px solid #000000;
-    }
-
-Table:
-
-    <html>
-
-        {{ HTML::style('css/table.css') }}
-
-        <!-- Cell styled with class -->
-        <td class="cell">Cell</td>
-
-        <!-- Cell styled with ID -->
-        <td id="cell">Cell</td>
-
-    </html>
-
-> Inside the reference guide you can find a list of supported styles.
-
-> It's advised to include `<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />` into the view to fix problems with UTF-8 encoding.

-# Passing variables to the view
-
-### As parameter
-
-We can pass variables to the view by using the second parameter inside the `loadView()` method.
-
-	$sheet->loadView('view', array('key' => 'value'));
-
-### With with()
-
-Alternatively you can use the `with()` method which works the same as with Laravel views.
-
-	// Using normal with()
-	$sheet->loadView('view')
-		  ->with('key', 'value');

-# Creating a sheet from an array
-
-## Array
-
-To create a new file from an array use `->fromArray($source, $nullValue, $startCell, $strictNullComparison, $headingGeneration)` inside the sheet closure.
-
-    Excel::create('Filename', function($excel) {
-
-        $excel->sheet('Sheetname', function($sheet) {
-
-            $sheet->fromArray(array(
-                array('data1', 'data2'),
-                array('data3', 'data4')
-            ));
-
-        });
-
-    })->export('xls');
-
-Alternatively you can use `->with()`.
-
-    $sheet->with(array(
-        array('data1', 'data2'),
-        array('data3', 'data4')
-    ));
-
-If you want to pass variables inside the closure, use `use($data)`
-
-    $data = array(
-        array('data1', 'data2'),
-        array('data3', 'data4')
-    );
-
-    Excel::create('Filename', function($excel) use($data) {
-
-        $excel->sheet('Sheetname', function($sheet) use($data) {
-
-            $sheet->fromArray($data);
-
-        });
-
-    })->export('xls');
-
-### Null comparision
-
-By default 0 is shown as an empty cell. If you want to change this behaviour, you can pass true as 4th parameter:
-
-    // Will show 0 as 0
-    $sheet->fromArray($data, null, 'A1', true);
-
->> To change the default behaviour, you can use `excel::export.sheets.strictNullComparison` config setting.
-
-## Eloquent model
-
-It's also possible to pass an Eloquent model and export it by using `->fromModel($model)`. The method accepts the same parameters as fromArray
-
-## Auto heading generation
-
-By default the export will use the keys of your array (or model attribute names) as first row (header column). To change this behaviour you can edit the default config setting (`excel::export.generate_heading_by_indices`) or pass `false` as 5th parameter:
-
-    // Won't auto generate heading columns
-    $sheet->fromArray($data, null, 'A1', false, false);

-# Calling PHPExcel's native methods
-
-It's possible to call all native PHPExcel methods on the `$excel` and `$sheet` objects.
-
-### Calling Workbook methods
-
-Example:
-
-    // Get default style for this workbook
-    $excel->getDefaultStyle();
-
-### Calling worksheet methods
-
-Example:
-
-    // Protect cells
-    $sheet->protectCells('A1', $password);

-# NewExcelFile injections
-
-Following the Laravel 5.0 philosophy with its new awesome FormRequest injections, we introduce you NewExcelFile injections.
-
-## NewExcelFile class
-
-This NewExcelFile is a wrapper for a new Excel file. Inside the `getFilename()` you can declare the wanted filename.
-
-    class UserListExport extends \Maatwebsite\Excel\Files\NewExcelFile {
-
-        public function getFilename()
-        {
-            return 'filename';
-        }
-    }
-
-## Usage
-
-You can inject these NewExcelFiles inside the __constructor or inside the method (when using Laravel 5.0), in e.g. the controller.
-
-    class ExampleController extends Controller {
-
-        public function exportUserList(UserListExport $export)
-        {
-            // work on the export
-            return $export->sheet('sheetName', function($sheet)
-            {
-
-            })->export('xls');
-        }
-
-    }
-
-## Export Handlers
-
-To decouple your Excel-export code completely from the controller, you can use the export handlers.
-
-    class ExampleController extends Controller {
-
-        public function exportUserList(UserListExport $export)
-        {
-            // Handle the export
-            $export->handleExport();
-        }
-
-    }
-
-The `handleExport()` method will dynamically call a handler class which is your class name appended with `Handler`
-
-    class UserListExportHandler implements \Maatwebsite\Excel\Files\ExportHandler {
-
-        public function handle(UserListExport $export)
-        {
-            // work on the export
-            return $export->sheet('sheetName', function($sheet)
-            {
-
-            })->export('xls');

-# Sheets
-
-### Creating a sheet
-
-To create a new sheet inside our newly created file, use `->sheet('Sheetname')`.
-
-    Excel::create('Filename', function($excel) {
-
-        $excel->sheet('Sheetname', function($sheet) {
-
-            // Sheet manipulation
-
-        });
-
-    })->export('xls');
-
-
-### Creating multiple sheets
-
-You can set as many sheets as you like inside the file:
-
-    Excel::create('Filename', function($excel) {
-
-        // Our first sheet
-        $excel->sheet('First sheet', function($sheet) {
-
-        });
-
-        // Our second sheet
-        $excel->sheet('Second sheet', function($sheet) {
-
-        });
-
-    })->export('xls');
-
-### Changing properties
-
-There are a couple of properties we can change inside the closure. Most of them are set to the config values by default. See `app/config/packages/maatwebsite/excel/config.php`.
-
-    Excel::create('Filename', function($excel) {
-
-        $excel->sheet('Sheetname', function($sheet) {
-
-            $sheet->setOrientation('landscape');
-
-        });
-
-    })->export('xls');
-
-> Go to the reference guide to see a list of available properties.
-
-### Default page margin
-
-It's possible to set the default page margin inside the config file `excel::export.sheets`.
-It accepts boolean, single value or array.
-
-To manually set the page margin you can use: `->setPageMargin()`
-
-    // Set top, right, bottom, left
-    $sheet->setPageMargin(array(
-        0.25, 0.30, 0.25, 0.30
-    ));
-
-    // Set all margins
-    $sheet->setPageMargin(0.25);
-    
-### Password protecting a sheet
-    
-A sheet can be password protected with `$sheet->protect()`:
-
-    // Default protect
-    $sheet->protect('password');
-    
-    // Advanced protect
-    $sheet->protect('password', function(\PHPExcel_Worksheet_Protection $protection) {
-        $protection->setSort(true);
-    });

-# Simple Excel Export
-
-### Basics
-
-A new file can be created using the `create` method with the filename as first parameter.
-
-    Excel::create('Filename');
-
-To manipulate the creation of the file you can use the callback
-
-    Excel::create('Filename', function($excel) {

-# Contribution Guide
-
-### Bug fixes
-
-**ALL** bug fixes should be made to appropriate branch (e.g. `1.1` for 1.1.* bug fixes). Bug fixes should never be sent to the `master` branch.
-
-### Pull Requests
-
-Every pull request should pass the unit tests. If you include new functionality, make sure you include a test. Pull requests will be evaluated and possibly added to the next stable release.
-
-### Feature Requests
-
-If you have an idea for a new feature you would like to see added to Laravel Excel, you may create an issue on GitHub with `[Request]` in the title. The feature request will then be reviewed by @Maatwebsite.
-
-### Coding Guidelines
-
-Laravel, and therefore Maatwebsite's Laravel Excel follows the [PSR-0](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md) and [PSR-1](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-1-basic-coding-standard.md) coding standards. In addition to these standards, below is a list of other coding standards that should be followed:
-
-- Namespace declarations should be on the same line as `<?php`.
-- Class opening `{` should be on the same line as the class name.
-- Function and control structure opening `{` should be on a separate line.
-- Interface and Trait names are suffixed with `Interface` (`FooInterface`) and `Trait` (`FooTrait`) respectively.

-# Import by Config
-
-When using advanced Excel files (e.g. without any heading columns), it can be complicated to import these.
-`->byConfig()` will help you handle this problem.
-
-Inside `excel::import.sheets` config you can find an example.
-
-    Excel::load('file.xls')->byConfig('excel::import.sheets', function($sheet) {
-
-        // The firstname getter will correspond with a cell coordinate set inside the config
-        $firstname = $sheet->firstname;
-
-    });
-
-> **Note:** if you are using multiple sheets. `->byConfig` will loop through all sheets. If these getters are only exist on one sheet, you can always use `->selectSheets()`.

-# Dates
-
-By default the dates will be parsed as a **[Carbon object](https://github.com/briannesbitt/Carbon)**. You can disable date formatting completly inside `import.php` by setting `dates.enabled` to `false`.
-
-To enable/disable date formatting for a single import, use `->formatDates($boolean, $format)`
-
-    // Format the dates
-    $reader->formatDates(true);
-
-    // Disable date formatting
-    $reader->formatDates(false);

-    // Format dates + set date format
-    $reader->formatDates(true, 'Y-m-d');
-
-### Format dates
-
-By default the dates are **not formatted**, but returned as a Carbon object. There are a couple of options to format them.
-
-#### Formatting results after ->get()
-
-Inside your loop you can utilise the Carbon method `->format($dateFormat)`
-
-    $rows->each(function($row) {
-
-        $created_at = $row->created_at->format('Y-m-d');
-
-    });
-
-#### Setting a default date format
-
-Inside the config you can set a default date format. A Carbon object will no longer be returned.
-
-Or you can use `->setDateFormat()`
-
-    $reader->setDateFormat('Y-m-d');
-
-### Setting custom date columns
-
-Cells which are not Excel formatted dates will not be parsed as a date. To force this behaviour (or to use this with CSV imports), you can set these date columns manually: `->setDateColumns()`
-
-    $reader->setDateColumns(array(
-        'created_at',
-        'deleted_at'
-    ))->get();

-# Extra
-
-### Disable using first row as collection attributes
-
-By default we will use the first row of a file as table heading (so as attribute names for the collection).
-You can change the default behaviour inside `import.php` with `import.heading`.
-
-To disable this for a single import, use `->noHeading()`.
-
-    $reader->noHeading();
-
-### Setting the cell name separator
-By default collection attribute names will be set by looking at the first row columns. Spaces will be translated to `_`.
-
-**E.g. Created at -> created_at**
-
-The default behaviour can be changed inside the `import.php` config by changing `'separator'`. Or you can use `->setSeparator($separator)`.
-
-    $reader->setSeparator('-');
-
-### Ignoring empty cells
-By default empty cells will not be ignored and presented as null inside the cell collection.
-
-To change the default behaviour, you can change `'ignoreEmpty`' inside `import.php` or use `->ignoreEmpty()`.
-
-    $reader->ignoreEmpty();
-
-### Input encoding
-
-Inside the `import.php` config you can change the input encoding. In most cases **UTF-8** will be the best solution. Hower if you dump your results make sure your HTML page has this exact same meta charset!
-
-Optionally you can pass the input encoding inside the `->load()` method.
-
-    // When utilising a closure, you can pass the input encoding as third parameter.
-    Excel::load('filename.csv', function($reader) {
-
-    }, 'UTF-8');
-
-    // or without a closure, you can use it as second parameter.
-    Excel::load('filename.csv', 'UTF-8');
-
-### CSV Settings
-
-Inside the `csv.php` config you can change the default settings, like the `delimiter`, the `enclosure` and the `line_ending`.

-# Custom formatting values
-
-By default Laravel Excel uses PHPExcel's default value binder to intelligently format a cells value when reading it. You may override this behavior by passing in your own value binder to suit your specific needs. Value binders must implement PHPExcel_Cell_IValueBinder and have a bindValue method. They may also extend PHPExcel_Cell_DefaultValueBinder to return the default behavior.
-    
-    use PHPExcel_Cell;
-    use PHPExcel_Cell_DataType;
-    use PHPExcel_Cell_IValueBinder;
-    use PHPExcel_Cell_DefaultValueBinder;
-
-    class MyValueBinder extends PHPExcel_Cell_DefaultValueBinder implements PHPExcel_Cell_IValueBinder
-    {
-        public function bindValue(PHPExcel_Cell $cell, $value = null)
-        {
-            if (is_numeric($value))
-            {
-                $cell->setValueExplicit($value, PHPExcel_Cell_DataType::TYPE_NUMERIC);
-
-                return true;
-            }
-            
-            // else return default behavior
-            return parent::bindValue($cell, $value);
-        }
-    }
-
-    $myValueBinder = new MyValueBinder;
-
-    Excel::setValueBinder($myValueBinder)->load('file.xls', function($reader) {
-
-        // reader methods
-
-    });
-
-Available PHPExcel_Cell_DataType's are TYPE_STRING, TYPE_FORMULA, TYPE_NUMERIC, TYPE_BOOL, TYPE_NULL, TYPE_INLINE and TYPE_ERROR
-
-To reset the value binder back to default and/or before calling Laravel Excel after setting a custom value binder you need to call the resetValueBinder method.
-
-    Excel::resetValueBinder();

-# ExcelFile injections
-
-Following the Laravel 5.0 philosophy with its new awesome FormRequest injections, we introduce you ExcelFile injections.
-
-## ExcelFile class
-
-This class is a wrapper for a file on your server. Inside the `getFile()` method you return the filename and it's location. Inside the `getFilters()` method you can enable filters, like the chunk filter.
-
-    class UserListImport extends \Maatwebsite\Excel\Files\ExcelFile {
-
-        public function getFile()
-        {
-            return storage_path('exports') . '/file.csv';
-        }
-
-        public function getFilters()
-        {
-            return [
-                'chunk'
-            ];
-        }
-
-    }
-
-If you want to have the `getFile()` dynamic based on user's input, you can easily do:
-
-    public function getFile()
-    {
-        // Import a user provided file
-        $file = Input::file('report');
-        $filename = $this->doSomethingLikeUpload($file);
-
-        // Return it's location
-        return $filename;
-    }
-
-## Usage
-
-You can inject these ExcelFiles inside the __constructor or inside the method (when using Laravel 5.0), in e.g. the controller.
-
-    class ExampleController extends Controller {
-
-        public function importUserList(UserListImport $import)
-        {
-            // get the results
-            $results = $import->get();
-        }
-
-    }
-
-## CSV Settings
-
-You can pass through optional CSV settings, like `$delimiter`, `$enclosure` and `$lineEnding` as protected properties of the class.
-
-    class UserListImport extends \Maatwebsite\Excel\Files\ExcelFile {
-
-        protected $delimiter  = ',';
-        protected $enclosure  = '"';
-        protected $lineEnding = '\r\n';
-
-    }
-
-## Import Handlers
-
-To decouple your Excel-import code completely from the controller, you can use the import handlers.
-
-    class ExampleController extends Controller {
-
-        public function importUserList(UserListImport $import)
-        {
-            // Handle the import
-            $import->handleImport();
-        }
-
-    }
-
-The `handleImport()` method will dynamically call a handler class which is your class name appended with `Handler`
-
-    class UserListImportHandler implements \Maatwebsite\Excel\Files\ImportHandler {
-
-        public function handle(UserListImport $import)
-        {
-            // get the results
-            $results = $import->get();
-        }
-
-    }

-# Handling imported results
-
-### Getting all sheets and rows
-
-After you have loaded a file, you can `->get()` the results like so:
-
-    Excel::load('file.xls', function($reader) {
-
-    })->get();
-
-or
-
-    Excel::load('file.xls', function($reader) {
-
-        // Getting all results
-        $results = $reader->get();
-
-        // ->all() is a wrapper for ->get() and will work the same
-        $results = $reader->all();
-
-    });
-
-> The `->get()` and `->all()` methods will return a sheet or row collection, depending on the amount of sheets the file has. You can disable this feature inside the `import.php` config by setting `'force_sheets_collection'` to `true`. When set to true it will always return a sheet collection.
-
-### Table heading as attributes
-
-By default the first row of the excel file will be used as attributes.
-
-    // Get the firstname
-    $row->firstname;
-
-> **Note**: by default these attributes will be converted to a slug. You can change the default inside the config `excel::import.heading`. Available options are: `true|false|slugged|ascii|numeric|hashed|trans|original`
-
-> True and slugged will be converted to ASCII as well when `excel::import.to_ascii` is set to true. You can change the default separator as well inside the config.
-
-### Collections
-
-Sheets, rows and cells are collections, this means after doing a `->get()` you can use all default collection methods.
-
-    // E.g. group the results
-    $reader->get()->groupBy('firstname');
-
-### Getting the first sheet or row
-
-To get the first sheet or row, you can utilise `->first()`.
-
-    $reader->first();
-
-> **Note:** depending on the config `'force_sheets_collection'` it will return the first row or sheet.
-
-### Workbook and sheet title
-
-It's possible to retrieve the workbook and sheet title with `->getTitle()`.
-
-    // Get workbook title
-    $workbookTitle = $reader->getTitle();
-
-    foreach($reader as $sheet)
-    {
-        // get sheet title
-        $sheetTitle = $sheet->getTitle();
-    }
-
-### Limiting the results
-
-##### Taking rows
-
-When you only want to return the first x rows of a sheet, you can use `->take()` or `->limit()`.
-
-    // You can either use ->take()
-    $reader->take(10);
-
-    // Or ->limit()
-    $reader->limit(10);
-
-##### Skipping rows
-
-When you want to skip a certain amount of rows you can use `->skip()` or `->limit(false, 10)`
-
-    // Skip 10 results
-    $reader->skip(10);
-
-    // Skip 10 results with limit, but return all other rows
-    $reader->limit(false, 10);
-
-    // Skip and take
-    $reader->skip(10)->take(10);
-
-    // Limit with skip and take
-    $reader->($skip, $take);
-
-### Result mutators
-
-When you want to get an array instead of an object, you can use `->toArray()`.
-
-    $reader->toArray();
-
-When you want an object, you can alternativly (instead of get() or all()) use `->toObject()`.
-
-    $reader->toObject();
-
-### Displaying results
-
-You can dump the results to a readable output by using `->dump()` or `->dd()`.
-
-    // Dump the results
-    $reader->dump();
-
-    // Dump results and die
-    $reader->dd();
-
-### Iterating the results
-
-You can iterate the results by using `->each()`.
-
-    // Loop through all sheets
-    $reader->each(function($sheet) {
-
-        // Loop through all rows
-        $sheet->each(function($row) {
-
-        });
-
-    });
-
-> Alternatively you can also `foreach` the results.

-# Selecting sheets and columns
-
-### Selecting one specific sheet
-If you want to select a single sheet, you can use `->selectSheets($name)`. Only that sheet will be loaded.
-
-    Excel::selectSheets('sheet1')->load();
-
-### Selecting multiple sheets
-If you want to select multiple sheets inside your file, you can pass an array as the parameter;
-
-    Excel::selectSheets('sheet1', 'sheet2')->load();
-
-### Selecting sheets by index
-
-    // First sheet
-    Excel::selectSheetsByIndex(0)->load();
-
-    // First and second sheet
-    Excel::selectSheetsByIndex(0, 1)->load();
-
-### Selecting columns
-
-If you want to select only a couple of columns, you can use `->select($columns)` or pass an array as the first parameter of `->get($columns)`.
-
-    // Select
-    $reader->select(array('firstname', 'lastname'))->get();
-
-    // Or
-    $reader->get(array('firstname', 'lastname'));
-
-> All get methods (like all(), first(), dump(), toArray(), ...) accept an array of columns.
