arcgis2geojson
A Python library for converting ArcGIS JSON to GeoJSON
Decision gist · record as of 2026-08-14
Yes. The package solves a specific, well-defined problem with zero external dependencies, permissive licensing, active maintenance, and no known vulnerabilities. Install it if you need to convert ArcGIS JSON to GeoJSON; skip it if you work exclusively with one format.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low friction: pure Python wheel with no runtime dependencies.
- Actively maintained as of 2026-08-10 with recent release history.

What it is and what it does
arcgis2geojson is a format converter that transforms ArcGIS JSON objects into GeoJSON-compliant Feature objects. It accepts input as either JSON strings or Python dictionaries and returns the corresponding GeoJSON format, preserving attributes as properties and converting ArcGIS geometry structures (rings, spatial references) into standard GeoJSON coordinate arrays. The package includes both a Python library API and a command-line tool for batch conversion or piped processing.
The library is a partial port of ESRI's official arcgis-to-geojson-utils, originally Apache 2.0 licensed but relicensed here under MIT. It has no external runtime dependencies, making installation straightforward. The package actively supports modern Python versions (3.10 through 3.14) and has been maintained since 2017, with recent activity as of August 2026.
Use it for
- Convert ArcGIS REST API responses to GeoJSON for use in web mapping libraries like Leaflet or Mapbox
- Batch-process ArcGIS JSON export files to GeoJSON format via the command-line tool for data pipeline workflows
- Integrate ArcGIS data sources into GeoJSON-based geospatial analysis or visualization tools
- Transform spatial attributes and geometries from ArcGIS services for interoperability with GeoJSON-native systems
- Pipe ArcGIS JSON data through the CLI for real-time format conversion in shell scripts or data ETL processes
