About Esri JSON

Esri JSON is the native JSON format used by Esri's ArcGIS REST API for returning query results from Feature Services and Map Services. It uses a similar structure to GeoJSON but with Esri-specific geometry encoding, spatial reference definitions, and field type metadata.

You might convert from Esri JSON when you have queried an ArcGIS REST API and need to use the results in a non-Esri tool, when you want to display the features on a web map that expects GeoJSON, or when you need to perform spatial operations in an open-source GIS.

Frequently asked questions

How do I obtain an Esri JSON file from an ArcGIS service?

Query the Feature Service REST endpoint with the f=json parameter. Copy the response JSON and save it as a .json file, or use the service's Query page to download results directly.

What is the difference between Esri JSON and GeoJSON?

The main differences are geometry encoding (Esri uses "rings" and "paths" rather than GeoJSON coordinate arrays) and spatial reference (Esri uses wkid codes rather than CRS URIs). Both represent the same features but are not directly interchangeable.

Will the spatial reference be preserved after conversion?

Yes — the wkid from the spatialReference object in the Esri JSON is used to determine the source CRS, and the output is reprojected to WGS 84 (EPSG:4326) automatically.
