Get automatic alerts when spreadsheet tabs change
The structure of a spreadsheet (its sheet/tab names) often changes as projects evolve, but these changes aren't communicated. Notis monitors your worksheet names and posts to Slack when sheets are added, deleted, or renamed, so your team stays oriented.
Trigger
Worksheet Names Changed
Triggers when the set of worksheet/tab names changes in a Google Spreadsheet. Detects when sheets are added, deleted, or renamed.
Action
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
When sheets are renamed or deleted, formulas that reference those sheets can break, and team members get confused about what happened. Without alerts, these structural changes go unnoticed.
- Instantly know when spreadsheet structure changes
- Catch broken formula references before they cause problems
- Stay aligned on which sheets exist and their purpose
- Coordinate structural changes across your team
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Slack to Notis.
- 2Create an automation with this prompt: 'When a worksheet is added, deleted, or renamed in my spreadsheet, post an alert to #[channel-name] with the change details.'
- 3Select 'Worksheet Names Changed' as the trigger.
- 4Choose the Slack channel for structural change notifications.
- 5Test by adding or renaming a sheet and confirm the Slack alert appears.
Questions about this workflow
Can I get alerts only for additions or deletions, not renames?
Yes. In your prompt, specify: 'Alert me only when sheets are added or deleted, not when they're renamed.'
Does this affect formulas that reference sheet names?
Sheet deletions can break formulas that reference those sheets. This automation gives your team a heads-up so they can update broken references.
Can I prevent accidental sheet deletion by alerting on attempts?
Yes. This automation alerts after deletion. To prevent it, consider protecting your spreadsheet or setting up separate access controls.

Supported Triggers and Actions
Notis builds workflows that link Google Sheets to Slack. A trigger fires from one place; an action lands in another.
Google Sheets triggers
Slack actions
Recurring trigger

Add an emoji alias
Adds an alias for an existing custom emoji in a slack enterprise grid organization.
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.
Add a remote file
Adds a reference to an external file (e.g., google drive, dropbox) to slack for discovery and sharing, requiring a unique `external id` and an `external url` accessible by slack.
Conditional Format Rule Changed

Developer Metadata Changed
Triggers when developer metadata entries change (new/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
Add emoji
Adds a custom emoji to a slack workspace given a unique name and an image url; subject to workspace emoji limits.
Filtered Range Values Changed
Polling trigger that monitors Google Sheets filtered ranges for value changes. Uses snapshot-based diffing to detect when values matching a data filter change. Emits the matched values when changes are detected.
Add reaction to message
