Google Sheets Connection Error in Looker Studio

Google Sheets is the most popular source — and most error-prone.

Permission Denied

Creator account needs Viewer access to the Sheet. Re-authorize if sharing changed. Share with "Anyone in your organisation" for teams.

Range Errors

Custom ranges break if columns change. Connect to entire sheet without custom range for robustness.

Type Issues

Mixed types in columns cause misidentification. Ensure consistent formatting. See best practices.

Stale Data

Caching issue. Resource → Data freshness → reduce cache duration. Set to 15 minutes for near-real-time.

Tab Renamed

Renaming Sheet tabs breaks connection. Update data source config immediately. Contact us for help.
