Geocoded address list from a Google Drive file to Google Sheets

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

The prompt

Using the rows in this CSV or Excel file in my Google Drive: <link to the file>, add the latitude, longitude and how sure the match is for every address, and put the results in a new tab of this Google Sheet: <link to a sheet>.

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.

Geocoded address list 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. Paste the prompt above.

Before you start

Reading a Google Drive file

Share the file with InstaMaps, or set it to "anyone with the link can view". InstaMaps reads it straight from Drive.

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 CSV or Excel file in my Google Drive: <link to the file>, add the latitude, longitude and how sure the match is for every address, and put the results in a new tab of this Google Sheet: <link to a sheet>.

  • 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.
