Open Extensions → Sheet2Cal → Set Up Sheet. Sheet2Cal creates the dates tab and the columns used by its event workflow.
Add one event per row, select the rows you want to process, then choose Create Calendar Events from the Sheet2Cal menu.
Pro users can sync row changes back to existing events. Use Import Calendar Events to bring a calendar date range into the dates sheet.
Close the spreadsheet completely, reopen it, and check Extensions → Sheet2Cal. If only Help appears, refresh once more and confirm you installed Sheet2Cal for the account currently open in Sheets.
Confirm the calendar is visible in Google Calendar and that your account has permission to make changes to events—not only view availability.
Sheet2Cal skips event IDs already present in the dates sheet. This prevents duplicate rows when you import the same date range again.
Use the same Google account used at checkout, open Upgrade to Pro, and select Refresh access. If it still does not update, include the purchase email when contacting support.
Send the Google account email, the operation you were running, and the exact error message. Do not send spreadsheet or calendar data that you do not want included in a support request.
