GeoJSON
View, validate, edit, and convert web-ready GeoJSON data.
Browser-based GIS workflow
Open an existing GeoJSON file, create new features, validate RFC 7946 structure, or convert a finished layer for desktop GIS and web-map workflows — all in your browser.
Start here: Start with a .geojson or .json file, or create a new FeatureCollection in the GeoJSON editor.
Choose a task
Use these tools to preview geometry and attributes before publishing or converting data.
Open GeoJSON or JSON on an interactive map and inspect features and attributes locally.
ValidateCheck GeoJSON structure, coordinates, and RFC 7946 compatibility before sharing a file.
Map extentDraw or enter a bounding box and export its extent as GeoJSON, WKT, or a map URL.
Create a new layer on a map or export an existing file into the format your next tool needs.
Draw and edit standard geometry, arrows, sectors, and curves, then export GeoJSON.
Desktop GISConvert GeoJSON into a Shapefile package for established GIS workflows.
Web mapsBuild a PMTiles archive from GeoJSON for compact, distributable map delivery.
Portable dataConvert a GeoJSON layer into a portable GeoPackage for modern GIS workflows.
Suggested workflow
Preview the map and inspect its attributes.
Open the viewer →Catch coordinate and FeatureCollection issues before publishing.
Validate GeoJSON →Create or refine geometry in the browser-based editor.
Open the editor →Choose Shapefile, GeoPackage, or PMTiles for the destination tool.
Convert to PMTiles →Frequently asked questions
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.
The viewer accepts .geojson files and JSON documents that contain valid GeoJSON. GeoJSON uses longitude/latitude coordinates in WGS 84 under RFC 7946.
GeoDataViewer processes files locally in your browser. Your GIS data is not uploaded to a server for viewing, validation, drawing, or conversion.
