Bulk create Google Calendar events from Google Sheets

✅ What This Workflow Does

This workflow automates the process of creating Google Calendar events from a Google Sheet. It ensures each row in the sheet is evaluated for its current status and: Creates new events in Google Calendar for rows marked as pending or failed. Updates the Google Sheet with the result: Created, Failed, or Duplicate. Handles errors gracefully and prevents duplicate event creation.

🛠️ How It Works

Manual Trigger: Start the workflow. Read Sheet: Fetch all rows from the configured Google Sheet. Check Status: If status is pending or failed, continue to event creation. If already created, update sheet as duplicate.

Create Event: Attempt to create a Google Calendar event using the row’s data.

Check for Errors: If the creation succeeds, update the sheet as Created.

If it fails, update the sheet as Failed.

Update Sheet: Reflect the result (Created, Failed, Duplicate) for each row.

This ensures a reliable workflow where the Google Sheet and Google Calendar remain synchronized without manual intervention.
