Why Is the Google Sheets Append Function Not Working with n8n Service Account?

Hi,
I am new to n8n and really enjoying it so far. However, I’m having trouble getting the Google Sheets append function to work. While the read function operates correctly, writing data via the append node appears to fail. I have watched several tutorial videos, but I still can’t make it work.
I'm currently using service account authentication instead of OAuth2. Could this be the issue? Additionally, when I run the append node, Google Sheets indicates “Last edit was seconds ago,” but no updates are visible in the sheet.
Any assistance or suggestions would be greatly appreciated. Thanks!

Below are a couple of things to check and try:
1. Check File Sharing with the Service Account
When using a service account, ensure that your Google Sheet is shared with the service account email address. If it isn’t shared, the node might make an API call (which can register as an edit) without actually updating the visible content. In Google Drive, open the Sheet’s sharing settings and add your service account email with Editor (or Viewer) permissions as needed.
2. Validate Data Formatting
If you’re appending an array, remember that the Google Sheets append operation expects the data in a valid JSON (key, value) format. If you’re appending raw arrays, consider using nodes like the [Split Out] or [Code] node to reformat your data properly before passing it to the append operation.
Additional Tips
- Refresh Column Mapping: If you changed column names after initially setting up your node, re-select Mapping Column Mode in your Google Sheets node so that the latest names are fetched.
- Check Logs: Review the execution logs within n8n to see if any errors or warnings are indicated, which might guide you further.
In summary, while service accounts are supported for the Google Sheets node, if the file isn’t shared with the service account, or if the data isn’t being formatted correctly, you may see the behavior you’re describing. Addressing these points should help get the append function working as expected.
