No Data Stored.

How it Works

01Paste or Upload Your CSV

Paste CSV text or upload a .csv file containing geographic data. Your CSV should have columns for latitude, longitude, and any additional properties to include in the GeoJSON.

02Map Latitude & Longitude Columns

Select which CSV columns contain the latitude and longitude values. The converter uses these to create GeoJSON Point geometry for each row.

03Preview the GeoJSON Output

The tool generates a GeoJSON FeatureCollection where each CSV row becomes a Feature with Point geometry and the remaining columns as properties.

04Download the GeoJSON File

Copy to clipboard or download as a .geojson file ready to load into Mapbox, Leaflet, QGIS, Google Maps, or any GeoJSON-compatible mapping tool.

Data conversion is one of those tasks that should be simple but often isn't — especially when formats have subtle variations, edge cases, and encoding quirks that trip up manual approaches. Our CSV to GeoJSON Converter was built to handle these real-world complexities cleanly, giving you accurate, properly formatted output every time without requiring technical expertise or specialized software.

The tool supports all the common variations and configurations you're likely to encounter, with automatic detection of common format quirks and clear error messaging when inputs don't match expected patterns. Whether you're converting a handful of records or a large dataset, the process is the same: paste or upload your input, optionally adjust any settings, and download or copy your converted output.

Built for developers, data analysts, students, and business users alike, this converter prioritizes accuracy and ease of use above everything else. It's completely free, runs in your browser, and never stores your data after processing. Bookmark it — you'll come back to it.

Can I map custom coordinate columns?
Yes. While the tool auto-detects common headers like 'lat' and 'lon', you can manually select any column as your coordinate source in the results interface.
Does it support non-point geometries?
Currently, this converter is designed for Point data (latitude/longitude pairs). It doesn't support lines or polygons from standard CSV formats.
How do I use CSV to GeoJSON Converter?
Enter the required information or upload your file, and the tool provides your result instantly. It's designed to be as intuitive as possible.
Is CSV to GeoJSON Converter free?
Yes — completely free. No account, subscription, or hidden fees of any kind.
Is CSV to GeoJSON Converter accurate?
Yes — it uses standard formulas and methods to ensure reliable, accurate results every time.
Is my data kept private?
Yes — any data you enter is processed securely in your browser and never stored or shared with third parties.
