Keep table schema updates connected to their documentation
A changed column or inferred type can be the cue to revisit the reference page that explains how your data is organized.
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
Fetch Webpage Content
Your eyes: get page content for decision-making. use before: actions (find targets, understand state) use to verify: page transitions, major state changes, when actions seem to fail format: html=find elements | markdown=clean content | success rate: 99%
Why this helps
Schema updates can leave dashboards and teammates relying on outdated assumptions about column names or formats.
- Notice columns added, removed, or renamed.
- Fetch your data dictionary or schema guide.
- Give reviewers a useful documentation reference.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Browser tool once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis which data dictionary URL to fetch after a schema change.
- 4Pick the Table Schema Changed trigger and choose where run reports go.
- 5Test with one real schema change.

Supported Triggers and Actions
Notis builds workflows that link Google Sheets to Browser tool. A trigger fires from one place; an action lands in another.
Google Sheets triggers
Browser tool actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Copy Selected Text

Fetch Webpage Content
Your eyes: get page content for decision-making. use before: actions (find targets, understand state) use to verify: page transitions, major state changes, when actions seem to fail format: html=find elements | markdown=clean content | success rate: 99%
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.
Get Clipboard Content
Read current content from the system clipboard - essential for data transfer workflows, extracting copied text, and reading user-copied data for processing.
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.
Keyboard Shortcut
Execute keyboard shortcuts and key combinations - essential for copy/paste, navigation, and application commands that agents need for efficient browser automation.
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.
Mouse Click
Precision clicker: manual clicking with coordinates. pattern: fetchwebpage(html) → find element → estimate coordinates → click → verify hints: center buttons ~(640,350) | nav/header ~y=150 | content ~y=300-500 tip: try ±50px if first click misses | success rate: 85%
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.
Mouse Double Click
Execute a precise double click at specified screen coordinates - ideal for opening files, selecting text, or activating ui elements that require double click gestures.
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.
Mouse Down (Press and Hold)
Press and hold mouse button at coordinates - use for starting custom drag operations, text selections, or long-press interactions. must be followed by mouseup action to complete.
