GeoJSON to CSV Converter
Processing entirely on your device — large files may take a moment.
CSV is the common language of data — importing contacts, analytics exports and database dumps almost always expects CSV. If your files are still in GeoJSON format, this page is the shortcut: GeoJSON is the web-standard format for maps: points, lines and polygons with properties, consumed by every mapping library.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How GeoJSON compares to CSV
| GeoJSON | CSV | |
|---|---|---|
| Structure | FeatureCollection JSON | One flat table |
| Types / schema | Point / LineString / Polygon | Untyped (all strings) |
| Compatibility | Leaflet, Mapbox, QGIS, PostGIS | Excel, Sheets, databases, code |
| Best for | Web maps and data pipelines | Data exchange and bulk import |

About the GeoJSON format
GeoJSON is the map format the web agreed on: a FeatureCollection of points, lines and polygons, each carrying arbitrary properties, in plain JSON. Leaflet, Mapbox, D3, QGIS and PostGIS all consume it directly, which is why almost every GIS workflow ends with “export as GeoJSON”.
Converting the older formats into GeoJSON (SHP, KML, GPX) is the bridge from institutional and device data into anything a browser can draw.
+ Strengths
- ✓Consumed by every web mapping library
- ✓Plain JSON — easy to filter and edit
- ✓Properties travel with the geometry
! Limitations
- −Verbose for huge datasets
- −No built-in styling or symbology
About the CSV format
CSV (comma-separated values) is the lowest common denominator of tabular data: one table, rows as lines, columns separated by commas, everything plain text. Excel, Google Sheets, every database importer, every data-science library and every scripting language read it, which is why it has survived fifty years of format fashion.
Its weaknesses come from the same minimalism. There are no types (everything is a string until you decide otherwise), no formulas, one table per file, and dialect quirks are legendary: comma vs semicolon locales, quoting rules, and Excel's insistence on re-opening UTF-8 files without a BOM as mojibake. Clean, well-formed UTF-8 CSV with a BOM sidesteps nearly all of it.
+ Strengths
- ✓Universal: Excel, Sheets, databases and code all read it
- ✓Human-readable and diff-friendly
- ✓Streams well — process giant files line by line
! Limitations
- −No types, no formulas, no multiple sheets
- −Dialect chaos: delimiters, quoting, encoding
- −Nested or hierarchical data does not fit
Why convert GeoJSON to CSV?
Converting makes sense where the strengths of CSV meet what GeoJSON cannot give you. Universal: Excel, Sheets, databases and code all read it Meanwhile Verbose for huge datasets One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this GeoJSON to CSV converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
What about special characters and non-English text?
Everything is handled as UTF-8. When you export CSV for Excel, a UTF-8 BOM is included automatically so Chinese, Japanese, Korean and accented characters display correctly on both Windows and macOS.
How large can my GeoJSON file be?
Since everything runs locally in your browser, the real limit is your device memory rather than an upload cap. Files up to a few hundred megabytes are usually fine on a modern computer; extremely large ones simply take longer.
Is my data safe here?
Yes. The conversion is plain JavaScript running in your tab: the data is parsed and re-serialized in memory, never sent anywhere, and disappears when you close the page.
