Access Live PostgreSQL Data in Excel 365 Online (Excel for the web)

Microsoft Excel for the web represents a cloud-native iteration of Microsoft Excel. When integrated with CData Connect AI, you gain immediate access to PostgreSQL data directly from within Excel. This access facilitates data analysis, collaborative work, calculations, and more. This article provides a step-by-step guide on connecting to PostgreSQL within your Connect AI instance and accessing live PostgreSQL data in Excel for the web spreadsheets, whether for viewing or updating purposes.

CData Connect AI provides a pure cloud-to-cloud interface for PostgreSQL, allowing you to easily access live PostgreSQL data in Excel for the web. Simply use the Connect AI Add-In to query live data (or write your own). Using optimized data processing out of the box, CData Connect AI pushes all supported query operations (filters, JOINs, etc) directly to PostgreSQL, leveraging server-side processing to quickly return PostgreSQL data.

Configure PostgreSQL Connectivity for Excel

Connectivity to PostgreSQL from Excel is made possible through CData Connect AI. To work with PostgreSQL data from Excel, we start by creating and configuring a PostgreSQL connection.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "PostgreSQL" from the Add Connection panel

3. Enter the necessary authentication properties to connect to PostgreSQL.

   To connect to PostgreSQL, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the data provider connects to the user's default database.

   SSH Connectivity for PostgreSQL

   You can use SSH (Secure Shell) to authenticate with PostgreSQL, whether the instance is hosted on-premises or in supported cloud environments. SSH authentication ensures that access is encrypted (as compared to direct network connections).

   SSH Connections to PostgreSQL in Password Auth Mode

   To connect to PostgreSQL via SSH in Password Auth mode, set the following connection properties:

   • User: PostgreSQL User name
   • Password: PostgreSQL Password
   • Database: PostgreSQL database name
   • Server: PostgreSQL Server name
   • Port: PostgreSQL port number like 3306
   • UserSSH: "true"
   • SSHAuthMode: "Password"
   • SSHPort: SSH Port number
   • SSHServer: SSH Server name
   • SSHUser: SSH User name
   • SSHPassword: SSH Password

   SSH Connections to PostgreSQL in Public Key Auth Mode

   To connect to PostgreSQL via SSH in Password Auth mode, set the following connection properties:

   • User: PostgreSQL User name
   • Password: PostgreSQL Password
   • Database: PostgreSQL database name
   • Server: PostgreSQL Server name
   • Port: PostgreSQL port number like 3306
   • UserSSH: "true"
   • SSHAuthMode: "Public_Key"
   • SSHPort: SSH Port number
   • SSHServer: SSH Server name
   • SSHUser: SSH User name
   • SSHClientCret: the path for the public key certificate file
   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add PostgreSQL Connection page and update the User-based permissions.

With the connection configured, you are ready to connect to PostgreSQL data from Excel for the web.
