What changed report from Google Sheets to a Google Drive file

This run compared with the last: which places changed, and how. Ask your AI in plain English: it reads Google Sheets, InstaMaps does the location work, and the results land in a Google Drive file.

The prompt

Using the rows in this Google Sheet: <link to your sheet>, compare it with last month's tab and tell me which places changed and how, and save the results to my Google Drive as a CSV file called "What changed".

Replace the parts in <angle brackets>.

What comes back

  • Each place's values from both runs side by side
  • What changed for the columns you name
  • Anything that can't be placed or answered comes back with the reason. Nothing is dropped.

What changed report in Claude

Every plan, including Free. On Free, InstaMaps uses your one custom connector; Google Drive, Gmail and Google Calendar are directory connectors and don't count against it.

  1. In Claude, open Settings, then Connectors, and choose "Add custom connector".
  2. Name it InstaMaps and paste https://get-instamaps.com/mcp. Click Add.
  3. Click Connect and continue with Google. You land back in Claude, ready to ask.
  4. Add the Google Drive, Gmail or Google Calendar connector from the same Connectors page when the chain uses them.
  5. Paste the prompt above.

Before you start

Reading Google Sheets

Share the sheet with InstaMaps, or set it to "anyone with the link can view". InstaMaps reads it straight from Google, so a sheet of thousands of rows is one call, and nothing passes through the chat.

Writing to a Google Drive file

Your AI tool's Google Drive connector saves the file.

Run it on a schedule

Every Monday at 8am: using the rows in this Google Sheet: <link to your sheet>, compare it with last month's tab and tell me which places changed and how, and save the results to my Google Drive as a CSV file called "What changed".

  • Claude. Scheduled tasks run a prompt hourly, daily, on weekdays or weekly, with the connectors you've added. They need a paid plan (Pro, Max, Team or Enterprise), and on Pro and Max they run in the cloud, so your computer can be off.
  • ChatGPT. ChatGPT has scheduled tasks, but OpenAI doesn't yet say whether they can use a custom connector. Run the prompt by hand until it does.
  • Microsoft Copilot and Teams. Copilot Studio agents can run on a schedule with a Recurrence trigger. The run uses the agent author's sign-ins.
  • Gemini. Google doesn't yet say whether scheduled actions can use a custom app. Run the prompt by hand until it does.

Good to know

  • Compares up to six runs of the same places, matched on InstaMaps' place ID.
  • The connector is free: 5,000 tool calls a day per person, and a whole sheet read by link counts as one call.
