Make table structure changes easy to follow
Know when a column is added, removed, renamed, or changes inferred type or format.
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 Chat Completion
Tool to create a chat completion using DeepSeek models (deepseek-chat or deepseek-reasoner). Use when you need to generate AI responses to chat conversations. Supports streaming, tool/function calling, and various parameters to control generation behavior (temperature, max_tokens, etc.).
Why this helps
A changed table structure can break assumptions and slow down people who depend on the data.
- Catch changes to table columns and inferred types or formats.
- Get a readable schema change summary.
- Help downstream users notice when data structure shifts.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and DeepSeek once in the Notis portal.
- 2Create an automation and name the table it follows.
- 3Ask Notis to summarize detected column, type, and format changes from the event details.
- 4Choose Table Schema Changed as the trigger and select a report channel.
- 5Test with one real example schema change.
Questions about this workflow
What schema changes does the trigger detect?
It monitors columns added, removed, or renamed, as well as inferred type and format changes.
Can the workflow identify every downstream impact?
It can summarize the detected schema changes. Downstream dependencies need to be supplied if you want their impact assessed.

Supported Triggers and Actions
Notis builds workflows that link Google Sheets to DeepSeek. A trigger fires from one place; an action lands in another.
Google Sheets triggers
DeepSeek actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create Anthropic Message
Tool to create a model response using DeepSeek's Anthropic-compatible API format with support for system prompts, tool calling, streaming, and thinking mode. Use when you need to generate chat completions using the Anthropic Messages API format. Requires base_url='https://api.deepseek.com/anthropic' or metadata base_url ending with '/anthropic'. Supports extended thinking, function calling with tools, and streaming responses. Note: Images and documents are not supported in content blocks.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create Chat Completion
Tool to create a chat completion using DeepSeek models (deepseek-chat or deepseek-reasoner). Use when you need to generate AI responses to chat conversations. Supports streaming, tool/function calling, and various parameters to control generation behavior (temperature, max_tokens, etc.).
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.
Get User Balance
Tool to get user's current account balance including granted and topped-up balances with detailed breakdown by currency (CNY or USD). Use when you need to check if the user has sufficient balance for API calls or to view detailed balance information.
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.
List Models
Tool to list currently available DeepSeek models and provides basic information about each one such as the owner and availability. Use when you need to discover which models are available for API calls.
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.
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.
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.
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.
