Convert GeoJSON to CSV Online — Free & Instant
Exporting GeoJSON to CSV allows non-GIS users to work with geospatial data in spreadsheet and data science tools. The output CSV includes X (longitude) and Y (latitude) columns alongside all GeoJSON feature properties. Ideal for point datasets that need to be opened in Excel, Google Sheets, or loaded into pandas or R.
Converter
When to convert GeoJSON to CSV
- Sharing geospatial point data with non-GIS colleagues using Excel
- Loading location data into pandas, R, or data visualisation tools
- Importing into business intelligence dashboards (Tableau, Power BI)
- Batch geocoding or processing pipelines that require CSV input
How to convert GeoJSON to CSV
- 1
Upload GeoJSON
Drop your .geojson file on the upload zone.
- 2
Select CSV
Click CSV in the format panel.
- 3
Open in Excel
The CSV includes all properties plus X (lon) and Y (lat) columns.
About GeoJSON format
GeoJSON is an open standard geospatial data format based on JSON, defined in RFC 7946. It supports all geometry types (Point, LineString, Polygon, MultiPolygon, etc.) and arbitrary properties per feature. GeoJSON is the preferred format for web mapping because browsers can parse it natively and libraries like Leaflet, Mapbox GL, and D3 consume it directly. GitHub renders GeoJSON files on a map automatically. It uses WGS 84 (EPSG:4326) as its coordinate reference system.
Strengths
- +Native browser support (JSON)
- +Human-readable and editable
- +Single file — easy to share
- +First-class support in web mapping libraries
About CSV format
CSV (Comma-Separated Values) files containing geometry data typically include latitude and longitude columns (or X/Y columns for projected data). Many data providers distribute point datasets as CSV because they are easy to open in Excel, Python, and R. When converting from a vector format to CSV, Maparz outputs an X (longitude) and Y (latitude) column along with all attribute data. To convert CSV to GeoJSON, your file must have columns identifiable as longitude (x, lon, lng, longitude) and latitude (y, lat, latitude).
Strengths
- +Opens in Excel, Google Sheets, any spreadsheet
- +Human-readable and editable
- +Lightweight for point data
Frequently asked questions
What happens to polygon geometry in CSV?
CSV is not well-suited for polygon or line geometry. Coordinates are exported as X/Y centroid values for non-point geometry. Use GeoJSON or Shapefile for full geometry fidelity.
Can I re-import the CSV back to GeoJSON?
Yes. Use the csv-to-geojson tool on this site, selecting the X and Y columns as your coordinate fields.
