GeoJSON Viewer
Visualize, validate, edit and export GeoJSON data on an interactive map.
Free & unlimited
All GeoJSON parsing happens in your browser. Map tiles are served by OpenStreetMap — your IP address is visible to the tile provider when you view the map.
About this tool

Click any feature on the map to view its properties in a popup.
- 4
Edit and export
Modify feature properties or geometry, then export the updated GeoJSON.
- Use the zoom-to-fit button to automatically frame all features on the map.
- GeoJSON coordinates are in [longitude, latitude] order - the opposite of most people's intuition.
- Large GeoJSON files with thousands of features may render slowly - consider simplifying geometry first.
- Interactive map with zoom, pan, and click-to-inspect

- Feature property inspection in popups
- GeoJSON syntax validation with error reporting
