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 1. Manual Trigger: Start the workflow. 2. Read Sheet: Fetch all rows from the configured Google Sheet. 3. Check Status: - If status is pending or failed, continue to event creation. - If already created, update sheet as duplicate. 4. Create Event: Attempt to create a Google Calendar event using the row’s data. 5. Check for Errors: - If the creation succeeds, update the sheet as Created. - If it fails, update the sheet as Failed. 6. 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. 🧰 Setup Requirements To run this workflow, you need: 1. n8n account with workflow access. 2. Google Sheets OAuth2 credentials connected to your Google Sheet. 3. Google Calendar OAuth2 credentials connected to the target calendar. 4. A properly formatted Google Sheet with columns for event details (see below). 5. The workflow nodes must be authorized to read and write to both Google Sheets and Google Calendar. 🧩 Key Features - Manual Trigger: Start the workflow anytime. - Google Sheets Read/Write: Reads event data and updates status after processing. - Google Calendar Integration: Automatically creates events. - Error Handling: Detects errors during event creation and logs them in the sheet. - Duplicate Prevention: Rows already processed are marked as duplicates. - Dynamic Data Mapping: Pulls event details directly from the sheet to Google Calendar. 📂 Input Spreadsheet Format The workflow expects a sheet with the following columns: |summary|start|end|description|location|attendees|status| |-|-|-|-|-|-|-|- |Meeting A|2026-03-20T10:00:00+08:00|2026-03-20T11:00:00+08:00|Client discussion|Google Meet|[email protected]|pending |Meeting B|2026-03-21T10:00:00+08:00|2026-03-21T11:00:00+08:00|Client discussion|Zoom|[email protected],[email protected]|pending |Meeting C|2026-03-22T10:00:00+08:00|2026-03-22T11:00:00+08:00|Client discussion|Google Meet|[email protected]|created
