CSV to GeoJSON Converter
Comma-Separated Values (CSV) is the format used by Google Sheets, Microsoft Excel, Apple Numbers, Airtable, and Notion. Geographic JSON (GeoJSON) is what developers and GIS analysts building maps or running spatial queries need. This free converter takes a CSV file and produces a ready-to-use .geojson on the spot — everything runs in your browser, so your data never touches our server. Drop a file or paste text on the left, click convert, copy or download the result on the right.
Frequently asked questions
How do I convert CSV to GeoJSON?
Open this page, paste your CSV text or drop your .csv file into the input panel, keep the dropdown set to CSV on the left and GeoJSON on the right, then click Convert. The .geojson output appears on the right; copy it to your clipboard or download the file.
Is this CSV-to-GeoJSON converter free?
Yes, completely free. No signup, no watermark, no upload limits. The conversion runs entirely in your browser using open-source libraries.
Does my file get uploaded anywhere?
No. The converter is fully client-side — your CSV file is parsed by JavaScript running in your own browser tab and never leaves your computer. We have no server-side processing for these tools.
What's the difference between CSV and GeoJSON?
CSV is a flat spreadsheet format. It strips geometry down to lat/lng columns and is the universal way to move place data between tools. GeoJSON is a lightweight JSON-based standard. It's what modern web maps speak natively, with first-class support in Mapbox, Leaflet, and PostGIS.
Can I convert GeoJSON back to CSV?
Yes — switch the dropdowns or open our /tools/geojson-to-csv/ page. We support every directional pair between KML, GPX, GeoJSON, CSV, and Excel.
