Troubleshooting Guide
Resolve common settings issues on your own.
Why are some events failing with 'Invalid Date' in preview?
+
Ensure your Date column contains values in standard date format (e.g., YYYY-MM-DD or standard Google Sheets dates). If mapping start and end times, write them in standard format (e.g., 09:30 AM or 14:00).
How do I add checkboxes to new data rows?
+
The add-on checks for data rows when you open the sidebar or click "Refresh Selection". If you add new rows, you can add checkboxes manually (select cell, go to Insert > Checkbox) or reload the sidebar to let Sheets2GCal Sync inject them automatically.
What should I do if the add-on fails with a permission error?
+
This usually happens if you are logged in to multiple Google Accounts in the same browser window. Google Workspace Add-ons can conflict in multi-login environments. Try using an Incognito/Private window or ensuring you are only logged in to the account containing the target spreadsheet.
