Easy Tech TutsHow to Sync Google Sheets to Google Calendar Easily 2026
By Impran M N
Manually re-entering event details into Google Calendar after already tracking them in a spreadsheet is a waste of time. With a bit of Google Apps Script, you can build a direct link between your Sheet and your Calendar so events sync automatically. This guide covers structuring your data and writing the sync script.
01Prepare your spreadsheet columns
Set up mandatory columns for event titles, start times, and descriptions in your Google Sheet.
02Format dates and times correctly
Make sure your date and time cells are formatted properly to prevent syncing errors later.
03Find your Calendar ID
Locate and copy your Google Calendar ID, which the script will need to know where to send events.
04Open the Apps Script editor
Access the Google Apps Script environment from your spreadsheet's Extensions menu.
05Write the sync script
Paste and customize a script that maps your spreadsheet columns to the corresponding calendar event fields.
06Add a custom menu button
Set up a menu item inside Google Sheets so you can run the sync with one click, then grant the necessary account permissions and test it.
Frequently asked questions
Do I need coding experience to set this up?
Basic familiarity with Apps Script helps, but the process mainly involves pasting and customizing a script rather than writing one from scratch.
Will the sync update automatically, or do I need to run it manually?
As described, running the sync is triggered manually via a custom menu button, though it's possible to extend the script for automatic triggers.
What happens if my dates are formatted incorrectly?
Incorrectly formatted dates and times are a common cause of syncing errors, so it's worth double-checking cell formatting before running the script.
Do I need special permissions to run the script?
Yes, you'll need to grant your Google account permissions the first time you run the script so it can access your Calendar.
