Track Sheet Table Schema Changes in Linear
When your sheet's table structure changes (columns added, removed, or renamed), Notis creates a Linear issue documenting the change. Your team stays aware of data structure updates.
Trigger
Table Schema Changed
Polling trigger that detects when a table's schema changes in Google Sheets. Monitors columns added/removed/renamed and inferred type/format changes. Uses snapshot-based diffing to compare schemas between polls.
Action
Create linear issue
Creates a new issue in a specified linear project and team, requiring a title and description, and allowing for optional properties like assignee, state, priority, cycle, and due date.
Why this helps
Table schema changes in spreadsheets can break dependent automations or confuse team members about data structure, especially if not communicated.
- Table schema changes are immediately visible as Linear issues
- Create an audit trail of structural changes to your spreadsheets
- Alert dependent workflows and team members of table changes
- Reduce breakage from unannounced column removals or renames
- Document the reasoning behind schema changes for future reference
Setup
Build it in a few focused steps.
- 1In the Notis portal, create an automation with the prompt: 'When the table schema changes in my [Sheet Name] spreadsheet (columns added, removed, renamed, or type changed), create a Linear issue describing the schema change.'
- 2Select 'Table Schema Changed' as your trigger.
- 3Choose your notification channel.
- 4Test by adding, removing, or renaming a column in your sheet and confirming the Linear issue appears.
Questions about this workflow
How detailed is the schema change description?
Notis documents the specific column name, the change type (added/removed/renamed), and the new data type if applicable.
Can I ignore certain schema changes?
Yes. Specify in your prompt which types of changes matter, e.g., 'Only create an issue if a column is removed or a critical column is renamed, not if new columns are added.'
What if I add and remove columns simultaneously?
Notis batches the changes and creates a single Linear issue documenting all schema updates.

Supported Triggers and Actions
Notis builds workflows that link Google Sheets to Linear. A trigger fires from one place; an action lands in another.
Google Sheets triggers
Linear actions
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
Create linear attachment
Creates a new attachment and associates it with a specific, existing linear issue.
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.
Create a comment
Creates a new comment on a specified linear issue.
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.
Create linear issue
Creates a new issue in a specified linear project and team, requiring a title and description, and allowing for optional properties like assignee, state, priority, cycle, and due date.
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.
Get create issue default params
Fetches a linear team's default issue estimate and state, useful for pre-filling new issue forms.
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.
Create a label
Creates a new label in linear for a specified team, used to categorize and organize issues.
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.
Delete issue
Archives an existing linear issue by its id, which is linear's standard way of deleting issues; the operation is idempotent.
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.
Get all teams
Retrieves all teams from the linear workspace without requiring any parameters.
New Sheet Added in Google Spreadsheet
Polling trigger that detects when a new sheet is added to a Google Spreadsheet.
Download issue attachments
Downloads a specific attachment from a linear issue; the `file name` must include the correct file extension.
