One Cell Changes, Your Calendar Responds
Point Notis to the cells that matter most—launch dates, deadline adjustments, or status flags. The moment a value changes, a new calendar event captures it.
Trigger
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
Action
Create Event
Creates an event on a google calendar, needing rfc3339 utc start/end times (end after start) and write access to the calendar. by default, adds the organizer as an attendee unless exclude organizer is set to true.
Why this helps
When key dates or status flags shift in a spreadsheet, they're often forgotten on the calendar, creating misalignment and missed communications.
- Captures date changes the instant they happen
- Eliminates forgotten calendar updates
- Perfect for dynamic project timelines
- Reduces manual synchronization overhead
Setup
Build it in a few focused steps.
- 1Connect your integrations to Notis.
- 2Ask Notis: 'When cell B5 in my Project Timeline sheet changes, create a calendar event with the new launch date.'
- 3Specify the exact cell or range (e.g., 'cells B5 to C5').
- 4Select 'Cell Range Values Changed' as your trigger.
- 5Update one of those cells and confirm the event is created.
Questions about this workflow
Can I monitor multiple cells at once?
Yes. Specify a range like 'A1:A10' and Notis will trigger whenever any cell in that range changes.
What if the cell is empty or contains non-date text?
Notis uses what's in the cell to populate the event. If you want only date changes to trigger events, mention that in your prompt.
Does this create a new event each time the cell updates, or replace the old one?
By default, it creates a new event each time. If you want to update an existing event instead, tell Notis in your prompt.
