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

• 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.
