Green lines or Green Box in Google Docs can appear under two common circumstances: when your document is open in multiple tabs or devices, or when it's being edited in Suggestion Mode. These lines are visual cues provided by Google Docs to help identify specific collaborative or formatting activities but can become nuisances if they persist unexpectedly.
Types of Green Lines
1. Green Line with the Name Flag
This is a vertical line with a name tag with it. The name tag becomes visible when you hover over the line. If you try to get rid of the line with the name tag using the delete key, then it simply leads to the deletion of text and the line stays as it is.

2. Green line-like Rectangular Border
This line is like a rectangular block around a specific section where you are trying to type, even if just spaces. If you try to get rid of this rectangular green line using the delete key, the situation may worsen and you get more green lines like this:

Reasons for Green Line Appearance
1. The same document is open at multiple places
This means that the document you are working on is open at many locations at the same time.
2. The document is open in the suggesting mode
If you are working on the document in suggesting mode rather than in editing mode then also this green line is displayed in your document.
How to Remove Green Line in Google Docs
Quickly eliminate the green line in Google Docs with our easy guide. Learn simple steps to remove unwanted formatting and enhance the appearance of your document.
1. Remove a Green Line When a Document is Open at Multiple Places
A green line in Google Docs appears when the same document is open in multiple tabs, windows, or devices, as the tool treats it like collaboration. To remove it, close the document in extra tabs or on other devices where it’s open.
2. Fixing Green Lines in Suggestion Mode
Google Docs lets you share documents with others and control their access. For example, in view-only mode, they can’t edit. It offers three sharing modes.
- Editing: Gives you full control on the document. You can edit the document as you desire.
- Suggesting: Only allows one to add or remove content indirectly, as a suggestion. It is then upto the owner of the document if they want to accept or reject those suggestions.
- Viewing: Only allows a person to view and print the document.
When the document is open in suggesting mode, whatever changes you make are not immediately reflected in the document. Rather, they are stored as suggestions and appear as a green block in the Google document.
Thus, when you are working on a document directly, make sure that the document is open in editing mode. Here is how to set the document to editing mode:
Step 1: Click on the Suggesting Mode on Top Right Corner
Present in the extreme right of the ribbon, click on the dropdown next to the suggesting mode.

Step 2: Select the Editing Mode
Select the editing mode(the one with the pen icon) present at the top of the drop-down list.

Step 3: Accept or Reject the Suggestions
A box will appear on the right side of the screen. There you will see the choices of either accepting or removing the name. Click on the cross in the comment box to remove the suggestion. This will remove the corresponding text and the green line.
