GeoJSON Editor
Edit GeoJSON with a code editor and live map preview. Draw features directly on the map, validate structure, and export your data.
Edit GeoJSON Like a Pro
A full-featured GeoJSON editor with real-time map preview, drawing tools, and validation — right in your browser.
Live Map Preview
See your GeoJSON rendered on an interactive map as you type. Points, lines, and polygons are displayed with automatic styling. Edit the code and watch the map update in real time.
Draw on the Map
Create Point, LineString, and Polygon features by clicking directly on the map. Drawn features are automatically added to your GeoJSON code. Double-click to complete lines and polygons.
Real-time Validation
JSON syntax errors are highlighted inline as you type. GeoJSON structure validation checks for missing fields, invalid types, and unclosed polygon rings with clear error messages.
How to Use the GeoJSON Editor
Paste or Write GeoJSON
Enter your GeoJSON in the code editor on the left. The editor supports syntax highlighting, auto-formatting, and error detection. You can also import a .geojson file.
Preview on Map
Your GeoJSON is automatically rendered on the map on the right. Points appear as circles, lines as paths, and polygons as filled areas. Click 'Fit to Bounds' to zoom to your data.
Draw Features
Use the drawing tools to add Point, LineString, or Polygon features directly on the map. Each drawn feature is automatically added to your GeoJSON code.
Export Your Data
Copy the GeoJSON to your clipboard or export it as a .geojson file. Use the format button to pretty-print or the minify button to compress your data.
