Geocoded address list in Google Sheets

Latitude, longitude and how sure the match is, for every address. Ask your AI in plain English: it reads Google Sheets, InstaMaps does the location work, and the results land in Google Sheets.

The prompt

Using the rows in this Google Sheet: <link to your sheet>, add the latitude, longitude and how sure the match is for every address, and write the results into the same sheet as new columns beside the rows.

Replace the parts in <angle brackets>.

What comes back

  • Latitude and longitude
  • A confidence (high, medium or low) with the reason, such as "postcode centre"
  • The county or council
  • Anything that can't be placed or answered comes back with the reason. Nothing is dropped.

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. 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 Google Sheets

InstaMaps writes to the sheet itself: share it with the address the answer gives you, as Editor. It adds new dated columns or a new tab, and never overwrites a cell.

Run it on a schedule

Every Monday at 8am: using the rows in this Google Sheet: <link to your sheet>, add the latitude, longitude and how sure the match is for every address, and write the results into the same sheet as new columns beside the rows.

  • 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

  • Strongest in the US and Great Britain. Rows that can't be placed come back with the reason, never dropped.
  • The connector is free: 5,000 tool calls a day per person, and a whole sheet read by link counts as one call.
  • Rather do it without an AI? Use the free tool on our site.
