View GeoJSON Online in 3D
Inspect FeatureCollections, edit vector geometries, filter nested attributes, and render 3D extrusions directly in your browser with zero data upload.
Launch GeoEditor for GeoJSON
Instant hardware-accelerated 3D viewer. No installation or account required.
Why Engineers Choose GeoEditor for GeoJSON
Zero Server Upload
Your GeoJSON stays in your browser memory. No data is sent over the wire, meeting strict privacy and NDA requirements.
3D Height Extrusions
Map building height attributes directly to 3D polygon extrusions with customizable lighting and perspective pitch.
Attribute Table & SQL Filtering
Filter complex properties, search by attribute value, and inspect nested metadata instantly in an interactive data grid.
Vertex Geometry Editing
Snap to nodes, insert vertices, split polygons, and export modified features with valid GeoJSON syntax.

How to Open & Inspect GeoJSON in 3 Steps
Drag and Drop Your File
Drop your .geojson or .json file directly into the GeoEditor window or select it from your local disk.
Explore & Inspect Attributes
Click features on the map to inspect properties, adjust layer styling, and toggle 2D/3D camera pitch.
Edit or Export
Make topological edits, filter down features, or export to Shapefile, KML, or GeoParquet.
Frequently Asked Questions About GeoJSON
Are my GeoJSON files uploaded to your server?+
No. GeoEditor runs entirely inside your browser using WebAssembly and WebGL. Your spatial files never leave your device.
Can I visualize large GeoJSON files without crashing the browser?+
Yes. GeoEditor uses hardware-accelerated Deck.gl layers that can smoothly render hundreds of thousands of vector vertices without freezing the UI.
Can I convert GeoJSON to Shapefile or KML?+
Yes. The built-in client-side converter lets you export your inspected GeoJSON into zipped Shapefiles, KML, or high-performance GeoParquet.
