How It Works

1

Paste or Upload

Paste addresses one per line, or upload a CSV and choose which column has the address data.

2

Geocode

Google Maps converts each address to lat/lng. Street-level accuracy. Handles partial addresses, city/state, and postal codes.

3

Copy, Paste, and Map

Copy results to clipboard, paste into a Google Sheets tab named layer_Accounts, and load the map with the InstaMaps add-on. No file download needed.

Common Questions

How many addresses can I geocode at once?

100 addresses per batch. Run it as many times as you need — there's no daily limit or account required. For very large datasets, split your list into batches of 100 and download each result.

What address formats work?

Full street addresses work best: "123 Main St, New York, NY 10001". City and state alone work for regional precision: "Austin, TX". Postal codes work for broad geographic placement. PO Boxes will geocode to the post office location, not a physical address.

How accurate are the results?

Results use the Google Maps Geocoding API. Street-level addresses return rooftop or interpolated accuracy — accurate to within a few metres. City/state inputs are accurate to the city center. The "Status" column shows OK for successful geocodes. If an address fails, check for typos or missing state/country.

What do I do with the lat/lng once I have it?

Download the CSV, open it in Google Sheets, and install the InstaMaps add-on. Create a sheet tab named "layer_Accounts" (or any name starting with layer_), paste your data in, and open the InstaMaps add-on to map all your locations on an interactive Google Map — with automatic filters and route planning.

Is this actually free? What's the catch?

Yes, free. No credit card, no account, no limit on how many times you use it. InstaMaps is a free Google Sheets add-on. The geocoder is a standalone tool that helps you get your data ready to map. The only thing we ask: if it's useful, install InstaMaps.

Can I geocode non-US addresses?

Yes. The Google Maps Geocoding API covers addresses worldwide. Include the country name in the address for best results outside the US: "10 Downing Street, London, UK".
