Auto-Log Sheet Schema Changes to Airtable
You add a new column to your Google Sheet table or rename an existing column. Notis logs that structural change to your Airtable audit record, so you have a history of how your data model evolved.
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 Comment
Creates a new comment on a specific record within an airtable base and table.
Why this helps
Table schemas evolve over time, but without an audit trail, you forget why columns were added or what the old column names were. Reconstructing the history is tedious.
- Maintain an audit trail of table schema changes over time
- Understand why columns were added or renamed by reviewing the history
- Debug data issues by checking the schema history
- Simplify onboarding by showing table structure evolution
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Airtable to Notis.
- 2Tell Notis: 'When a table schema changes in my sheet (columns added/removed/renamed), log the change to my audit record in Airtable.' Notis configures this.
- 3Specify which Google Sheets table to monitor and which Airtable record should receive the audit comments.
- 4Describe comment format: 'Column added: [name]' or 'Column renamed from [old] to [new]' as you prefer.
- 5Test by adding or renaming a column in your Google Sheets table and confirming the change is logged in Airtable.
Questions about this workflow
What counts as a schema change?
Column additions, deletions, renamings, and type changes (e.g., text to number). Any modification to the table structure is logged.
Can I track only important schema changes?
Yes, filter to specific tables or columns: 'Only log changes to the Contact Info or Status table, ignore helper columns.'
Does this track formatting or sorting changes?
No, only structural changes (columns themselves). Formatting and sorting are separate operations.

Create Comment
Creates a new comment on a specific record within an airtable base and table.
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 Field
Creates a new field within a specified table in an airtable base.
Data Validation Rule Changed

Create multiple records
Creates multiple new records in a specified airtable table.
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 record
Creates a new record in a specified airtable table; field values must conform to the table's column types.
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.
Create table
Creates a new table within a specified existing airtable base, allowing definition of its name, description, and field structure.
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.
