See any GeoJSON on a map, click a feature to inspect and edit its properties, and export the result. Paste it below, drop a .geojson file anywhere on this page, load one from a link — or try the example.
You can also drag & drop a .geojson or .json file anywhere on this page. Loading from a URL only works if that server allows cross-origin requests (CORS) — if it refuses, download the file and drop it here instead.
