How to Use This Tool

This tool converts a CSV of coordinates into GeoJSON. Map the latitude and longitude columns (auto-detected where names are recognizable), and every row becomes a Point feature with your remaining columns as properties. Runs entirely in your browser — nothing is uploaded.

  1. Paste or upload your CSV — Any spreadsheet export with coordinate columns works.
  2. Check the mapping — Latitude and longitude are required; name and description are optional.
  3. Get your GeoJSON — Copy the result or save it as a .geojson file.

FAQ

4 questions
Does this tool upload my data?
No. The conversion happens entirely in your browser. Your data never leaves your device.
Which columns do I need?
Latitude and longitude are required — common names like lat, lon, lng, x, and y are auto-detected. Name and description are optional; every other column becomes a feature property.
What does the output look like?
A valid GeoJSON FeatureCollection with one Point feature per CSV row, ready for geojson.io, Mapbox, Leaflet, QGIS, or any GeoJSON consumer.
What happens to rows with bad coordinates?
Rows whose latitude/longitude can't be parsed or are out of range are skipped, and the tool tells you how many were dropped.
