Google Sheets Integration with Office 365, SharePoint and 100+


Google Sheets data can be integrated and synchronized codeless with various other data sources using the Layer2 Cloud Connector via 3rd party data providers. Please take a look here for supported target systems and applications like SQL, Office 365, SharePoint, Exchange, Dynamics and others.​



To connect to a Google sheet the source entity must be configured as follows in the Layer2 Cloud Connector Connection Manager:

Google Sheets Specific Integration Settings


​Please note the following Google Sheet specific settings.


  • Install the RSSBus ADO.NET Provider for Google AppsSheets. This provider is not part of the Layer2 Cloud Connector ADO.NET provider package and should be installed separately from the vendor's product page. It requires extra licensing.
  • Choose “RSSBus ADO.NET Provider for Google Spreadsheets” (exact name might vary) as “Data Provider” for your data entity (source and / or destination).
  • Follow the vendor instructions for setting up the connection string and select statement (see below for samples).
  • Set the connection string as required, e.g. OAuthClientId=myClientId; OAuthClientSecret=myClientSecret; InitiateOAuth=true; SpreadSheet=myTable
  • A Google client ID looks like
  • A client secret looks like one encoded string of numbers and characters.
  • myTable referrs to any specific table in the spreadsheet.
  • Note: The first time new credentials are used, your default browser will open a web page where you are asked to authorize access to your Google account. Thats not the case for any further manual or automatic scheduled syncs.
  • Set the data query as required, e.g. SELECT * mySheet.
  • Choosing a primary key is not required as the provider sets one automatically.
  • You can map your Google spreadesheet data fields to specific external fields in the Layer2 Cloud Connector. Please take care about data types (simple type conversions are supported).
  • No installation or changes are required at the Google spreadsheet data source or the data destination.
  • Data synchronization can be started manually in the Connection Manager, per command line or scheduled in background by the Layer2 Cloud Connector Windows Service. Only data changes are processed (no delete / bulk import).
  • No programming required for setup a connection and sync.
  • No need to open your local network for access from outside.
  • Insert to Google Sheet requires knowledge of the primary key value (e.g. customer number). Delete / Update works as usual, also two-way. If you are using this provider as target or in a bi-directional connection, choosing your own primary key (usual PK restrictions of ‘unique, non-NULL’ apply) is required. Choosing the automatically provided primary key is not recommended as this might lead to inconsistent synchronization. Using the replication key feature (see technical documentation for explanation) might help you with this.

Known Issues and Workarounds with Google Sheets Data Integration

  • There's a known issue with Cloud Connector version 7.8+ where it cannot properly open the verification page for Google's OAuth connection. Trying to verify the connection will result in a timeout message. There are workarounds for this, however. Please contact [email protected] for further help.

Step-by-Step Intros For Codeless Google Sheet Data Integration And Synchronization


Just some ideas what to connect next:
