Keep a PDF record of table schema changes
When the structure of a table shifts, generate a clear document that helps teammates catch up before relying on it.
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 Document
Tool to create a PDF or Excel document synchronously from HTML content or URL. Use when you need to generate a document file from HTML data. The document is returned immediately as a downloadable file. Either document_content or document_url must be provided, but not both.
Why this helps
Column names or inferred formats change quietly, leaving reports and teammates working from stale assumptions.
- Capture detected column additions, removals, renames, and inferred type changes.
- Make structural updates easier to review and communicate.
- Create a lightweight record for teams that rely on the table.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and DocRaptor once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a clear name and prompt.
- 3In one instruction, tell Notis to summarize the detected schema changes and create a data dictionary PDF from HTML.
- 4Choose the Table Schema Changed trigger and select where run reports should go.
- 5Test with one real schema change and review the generated PDF.
Questions about this workflow
What schema changes can the trigger detect?
It monitors columns added, removed, or renamed, plus inferred type and format changes.
Will it explain which dashboards are affected?
Only if that dependency information is available in the sheet or prompt. The schema event itself does not describe downstream dependencies.

Supported Triggers and Actions
Notis builds workflows that link Google Sheets to DocRaptor. A trigger fires from one place; an action lands in another.
Google Sheets triggers
DocRaptor actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create Async Document
Tool to create documents asynchronously from HTML content. Use when generating PDF, XLS, or XLSX documents and you need to poll for completion status or use a callback URL for notification.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create Document

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 Document from Referrer
Tool to convert webpages into documents using referrer-based authentication without an API key. Use when you need to generate PDFs or Excel files from registered domains without explicit API credentials.
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 Hosted Async Document
Tool to create a hosted document asynchronously. Use when you need to generate a PDF, XLS, or XLSX document and track its completion status via callback_url or the status API.
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.
Download Async Document
Tool to download a completed asynchronous document using the download URL from status response. Use when you have a download_id and need to retrieve the generated document file.
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 Async Document Status
Tool to check the status of an asynchronously created document. Use when monitoring progress of async documents by polling for completion status.
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.
List Documents (JSON)
Tool to retrieve a paginated list of previously created documents with metadata in JSON format. Use when you need to see document creation history or query past documents.
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.
List Documents (XML)
Tool to retrieve a paginated list of previously created documents with metadata in XML format. Use when you need to see document creation history or query past documents in XML format.
