Auto-Document Drive Files as Your Sheet Evolves
Add or rename columns in your sheet, and Notis updates the file descriptions in Drive to reflect your new data structure. Your documentation stays current.
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
Update File (Metadata)
Updates file metadata. uses patch semantics (partial update) as per google drive api v3. use this tool to modify attributes of an existing file like its name, description, or parent folders. note: this action currently supports metadata updates only. file content updates require multipart/related upload and are not yet implemented.
Why this helps
You add new columns to a tracking sheet, but the matching file description in Drive still describes the old structure. Team members don't know the data has evolved.
- File descriptions always reflect your current sheet structure
- Team understands data organization without manual updates
- No forgotten documentation when sheets evolve
Setup
Build it in a few focused steps.
- 1Connect both integrations to Notis
- 2Tell Notis: 'When my sheet's columns change, update the matching Drive file's description'
- 3Specify how the description should be formatted (list of columns, data types, etc.)
- 4Choose your notification channel
- 5Test by adding a column to your sheet and verifying the file description updates
Questions about this workflow
What information about the schema gets added to the description?
Column names, data types, and any validation rules can be included in the description.
Does this work for renamed columns?
Yes. Notis detects when columns are renamed or added and updates the file description accordingly.
