Frequently asked questions

GeoJSON tools FAQ

What can I do with a GeoJSON file online?

You can view its geometry and attributes, validate its structure, edit or create features, and convert the finished layer to formats such as Shapefile, GeoPackage, and PMTiles without installing desktop GIS software.

Which GeoJSON files can I open?

The viewer accepts .geojson files and JSON documents that contain valid GeoJSON. GeoJSON uses longitude/latitude coordinates in WGS 84 under RFC 7946.

Are GeoJSON tools private?

GeoDataViewer processes files locally in your browser. Your GIS data is not uploaded to a server for viewing, validation, drawing, or conversion.
