3 GeoJSON to CSV Tools, Compared Honestly
Manesh Jayawardhana

You’ve got a GeoJSON file — from a mapping tool, a GIS export, or an API — and need it as a CSV table so you can open it in a spreadsheet or load it into a database instead of a viewer that only reads GeoJSON.
The main things that differ between converters are where your file gets processed (locally in your browser versus uploaded to a server), how large a file you can convert for free, and how cleanly geometry data gets flattened into columns.
How to judge a GeoJSON to CSV tool
Processes files locally when possible. GeoJSON often contains real location data — processing it in your browser rather than uploading it to a server is the more private default.
Preserves all properties as columns. Every attribute field on each feature should map to a CSV column without silently dropping data.
Handles geometry sensibly. Whether that’s separate latitude/longitude columns for points or a geometry column for more complex shapes, the output should be usable in a spreadsheet.
Has a reasonable file size limit. Large exports from real GIS datasets can be sizable — check the limit matches what you’re actually converting.
The comparison
| Tool | Best for | Free tier | Watch out |
|---|---|---|---|
| Atlas | Large files, preserves coordinate reference system data | Free up to 250MB | Signup needed for extended limits and additional features |
| MyGeodata Cloud | Very large files, broad GIS/CAD format support | Free, up to 5GB | Server-side processing — your file is uploaded |
| Honeycomb Maps | Client-side privacy, optional lat/long column split for points | Free, no signup | Roughly 200MB practical limit depending on browser |
| GeoJSON to CSV | Flattens Feature/FeatureCollection into geometry and property columns | Free, no signup | No stated large-file handling beyond typical browser limits |
Facts checked August 2026; tools change their plans.
Atlas
Atlas converts GeoJSON to CSV for free on files up to 250MB, preserving all attribute data — properties, fields, and columns — along with geometry and coordinate reference system information, with no signup required for basic conversion.
It isn’t for someone processing much larger files or wanting extended features without an account — those require signing up.
MyGeodata Cloud
MyGeodata Cloud handles files up to 5GB (with ZIP/7z compression recommended for the largest ones), supports a wide range of vector and raster GIS/CAD formats beyond just CSV, transfers data over encrypted SSL, and automatically deletes files after processing.
It isn’t for someone who wants to avoid uploading data to a server at all — conversion happens server-side rather than in your browser.
Honeycomb Maps
Honeycomb Maps processes entirely client-side with no upload and no account, flattens geometries into GeoJSON, WKT, or WKB encodings with one row per feature, optionally splits point coordinates into separate latitude/longitude columns, and preserves all original properties as CSV columns.
It isn’t for someone converting very large datasets — it handles roughly 200MB depending on the browser and processes one file at a time.
GeoJSON to CSV
Our tool converts a GeoJSON Feature or FeatureCollection into a CSV table with geometry and property columns — entirely in your browser.
A real limitation: it doesn’t advertise specific large-file handling — for multi-gigabyte GIS exports, a server-side tool like MyGeodata Cloud is built for that scale.
Which one to pick
If you want a private, client-side conversion for a typical-sized GeoJSON file, use our GeoJSON to CSV converter or Honeycomb Maps.
If you’re converting a large file up to 250MB and want to stay signup-free, use Atlas.
If you’re working with a multi-gigabyte GIS export or need other format conversions, use MyGeodata Cloud.
If you specifically want separate latitude/longitude columns for point data, use Honeycomb Maps.
How to do it with GeoJSON to CSV
- Open the GeoJSON to CSV converter.
- Paste your GeoJSON Feature or FeatureCollection.
- Get a CSV table with geometry and property columns, ready to open in a spreadsheet.

Frequently asked questions
Is there a free GeoJSON to CSV converter that doesn’t need an account?
Yes. Our GeoJSON to CSV converter, Atlas (up to 250MB), and Honeycomb Maps all work without requiring signup — MyGeodata Cloud references account features though basic conversion may not require one.
Why would I want GeoJSON data in a CSV instead of keeping it as GeoJSON?
CSV opens directly in spreadsheet software like Excel or Google Sheets, works with tools that don’t understand geospatial formats, and is easier to filter, sort, or join with non-geographic data — GeoJSON, by contrast, is built for mapping libraries and GIS software that understand geometry natively, as defined in RFC 7946.
What happens to complex geometries like polygons when converting to CSV?
Unlike a single point with clear latitude/longitude values, a polygon or multi-line geometry doesn’t reduce cleanly to two columns — most converters store the full geometry as a single column using an encoding like WKT (Well-Known Text) or the original GeoJSON geometry object, which keeps the shape data intact but isn’t as immediately readable as separate coordinate columns.
Final thought
For a typical GeoJSON export, a client-side converter keeps your location data private and handles the job just as well as a server-side one — reach for a server-based tool only when your file exceeds what a browser can comfortably process.
