Make changes to your sheet's data structure easier to follow
Leave a clear note when a table's columns or inferred formats change between checks.
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 paper document
Creates a new dropbox paper document at the specified path using html or markdown content.
Why this helps
A changed column or inferred type can disrupt downstream work if collaborators do not notice the structural update.
- Surface added, removed, or renamed columns.
- Keep a readable record of inferred type and format changes.
- Help downstream users review structural updates.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Dropbox once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for the table schema.
- 3In one instruction, ask Notis to document detected column, type, or format changes in Dropbox Paper.
- 4Pick Table Schema Changed and choose where run reports go.
- 5Test with one real schema change and review the Paper note.
