How to Convert TopoJSON to GeoJSON Free, Step by Step
Need a GeoJSON from a TopoJSON? Here is how to convert TopoJSON to GeoJSON, what usually goes wrong, and how to get a file you can use first time.
Why convert TopoJSON to GeoJSON?
A GeoJSON is map features (points, lines, polygons) and their properties in plain JSON. Readable, web-native and the default format of Leaflet, Mapbox and most map libraries.
- Web maps.
- Sharing boundaries and routes.
- Data journalism.
Where most converters let you down
Plenty of tools will happily take your TopoJSON and give you something back. The trouble is what they give you: many drop properties, swap latitude and longitude, or need a GIS install. You only find out later, when the file will not cut, print, import or open the way you expected.
What you actually want is map data moved between formats with geometry and properties intact. That is the standard this TopoJSON to GeoJSON converter is built to.
How to convert TopoJSON to GeoJSON in 3 steps
- Open the TopoJSON to GeoJSON converter and drop in your TopoJSON.
- Check the result in the preview and adjust the settings if you need to.

What happens to your file
A TopoJSON is read in your browser with its geometry and properties, and drawn on a map so you can check it landed in the right place.
The conversion runs in your browser, so the file is never uploaded: client work, statements and unreleased designs stay on your computer.
Getting the best GeoJSON: mistakes to avoid
- If points appear in the wrong country, the source may have latitude and longitude the other way round.
- Shapefiles need their .shp, .dbf and .prj together; zip them up before uploading.
