Map file converter: GPX, KML, GeoJSON, CSV

Drop a GPX, KML, KMZ, GeoJSON or CSV file. The format is recognised, the map shows what is in it, and you download it in any of the others.

Which formats can I convert?

GPX, KML (and zipped KMZ), GeoJSON and CSV, each to any of the others: twelve directions, each with its own page below.

Is my file uploaded?

No. The file is read and converted in your browser; nothing is sent to a server.

What happens to tracks in a CSV?

A CSV has one point per row, so a track becomes its points in order. Converting a CSV, you can choose Track to join the rows back into a line.

Which program opens each format?

GPX: Garmin, Strava, most GPS apps and our GPX viewer. KML/KMZ: Google Earth and Google My Maps. GeoJSON: QGIS, Leaflet, Mapbox and our GeoJSON editor. CSV: Excel, Numbers, Google Sheets.

Is there an app?

Not for this tool yet. The nearest is GPX Explore, on iPhone, iPad and Mac, which opens any GPX file with the track coloured by grade, every sensor charted and a workout summary. Free. App Store · Mac App Store · More about GPX Explore
