Geocode CSV

Add latitude and longitude to every row in a CSV file using OpenStreetMap Nominatim. Select the address column, click start, and download the enriched file when done. Everything runs in your browser — no data is uploaded to any server.

Uses OpenStreetMap Nominatim — free but rate-limited to 1 request/second. Maximum 20 rows per run. Nothing is uploaded to any server; geocoding calls go directly from your browser to OpenStreetMap.
