Get automatic alerts when spreadsheet metadata changes
Changes to a spreadsheet's structure (named ranges, metadata, data connections) often go unnoticed, causing confusion or broken automations downstream. Notis monitors metadata changes and posts alerts to Slack, keeping your team aware of structural updates.
Trigger
Spreadsheet Metadata Changed
Polling trigger that detects when a Google Spreadsheet's metadata changes. Uses snapshot-based diffing to detect any changes in spreadsheet properties, sheets, named ranges, developer metadata, data sources, etc.
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
Spreadsheet metadata changes can break downstream automations or cause data misalignment. Without alerts, these changes go undetected until something breaks.
- Catch metadata changes before they break downstream automations
- Maintain visibility into spreadsheet structure updates
- Quickly identify when named ranges or data sources are modified
- Coordinate metadata 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 the metadata of my spreadsheet changes (named ranges, properties, or data sources), post an alert to #[channel-name].'
- 3Select 'Spreadsheet Metadata Changed' as the trigger.
- 4Choose the Slack channel for structural change notifications.
- 5Test by adding a named range or modifying a data source and confirm the Slack alert appears.
Questions about this workflow
What types of metadata changes trigger alerts?
Additions or modifications to named ranges, data sources, developer metadata, spreadsheet properties (like locale or timezone), and more.
Can I filter to only certain types of metadata changes?
Yes. In your prompt, specify what you care about: 'Alert me only when named ranges are added or removed.'
Who typically makes metadata changes that we should track?
Often developers or automation engineers updating named ranges or data connections. This automation keeps the team aware of structural changes.

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

Set snooze duration
Deprecated: turns on do not disturb mode for the current user, or changes its duration. use `set dnd duration` instead.

Conditional Format Rule Changed
Triggers when conditional formatting rules change in a Google Spreadsheet. Detects when rules are added, updated, or removed. Uses snapshot-based diffing to detect changes between polls.
Add an emoji alias

Data Validation Rule Changed
Triggers when data validation rules change (added/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
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.
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 a star to an item
Stars a channel, file, file comment, or a specific message in slack.
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 call participants
Registers new participants added to a slack call.
New Rows in Google Sheet
Simple polling trigger that monitors Google Sheets for new rows. Detects when new rows are added and returns the complete row data. Perfect for triggering any workflow based on new sheet entries.
