How to create Google Calendar™ events from a Google Sheet

Planning a rota, a content schedule, a training programme or a season of appointments is far faster in a spreadsheet than clicking events into a calendar one at a time. Here is how to turn sheet rows into calendar events in bulk.

The spreadsheet-first workflow

  1. Lay out one event per row: title, start, end, location, description, guests.
  2. Mark each new row NEW in a status column.
  3. Run a sync — each row becomes a real calendar event, and its event ID is written back to the row.

Because every row is matched to its event by ID, editing a row and re-syncing updates the same event rather than creating a duplicate — the failure that plagues most copy-paste and script approaches.

What to look for in a tool

Doing it by hand instead

Google offers no native bulk import from Sheets. The closest manual route is exporting your sheet to CSV, converting to ICS, and importing via Calendar settings — workable once, painful weekly, and it can only create events, never update or delete them.

CalWeave does all of the above in one click, both directions, with a delete safety cap so your calendar can never be wiped. Free 14-day trial, no card required.
