CSV Coordinates to GeoJSON Converter
Convert CSV files containing latitude and longitude coordinates into GeoJSON. Choose your coordinate columns, preview points on an interactive map and download a GeoJSON FeatureCollection.
Convert CSV Coordinates to GeoJSON
Upload a CSV file containing latitude and longitude columns.
Upload a CSV file to begin
The file should contain separate latitude and longitude columns.

Convert CSV Coordinates
Upload a CSV file containing latitude and longitude columns. The converter keeps the other CSV fields as GeoJSON feature properties while turning each valid row into a Point feature.
Preview Points on a Map
Review converted locations on an interactive map before downloading the GeoJSON file. This helps identify obvious coordinate problems or misplaced points.
Browser-Based Processing
CSV parsing and GeoJSON creation happen in your browser, so you can quickly prepare spatial point data without opening desktop GIS software.
How to Convert CSV Coordinates to GeoJSON
- Upload a CSV file that contains latitude and longitude coordinates.
- Select the latitude and longitude columns if they are not detected automatically.
- Optionally select a label column to make map popups easier to identify.
- Select Convert to GeoJSON to validate the coordinates and generate Point features.
- Review the points on the map and inspect the GeoJSON output.
- Download the finished .geojson file.
Common Uses & Real-Life Examples
CSV coordinate files are common in surveys, monitoring systems, field operations and business datasets. Converting them to GeoJSON makes the same information easier to use in web maps, dashboards and GIS applications.
Map survey or field locations
A survey team can convert a CSV containing facility names, latitude and longitude into GeoJSON and immediately inspect schools, clinics, project sites or interview locations on a map.
Prepare locations for a web map
A developer can convert office, store, branch or service locations from a spreadsheet export into GeoJSON before displaying the points in an online mapping application.
Convert GPS observations
GPS coordinates exported as CSV can be turned into GeoJSON Point features for use in QGIS, ArcGIS, web maps or spatial analysis workflows.
Map monitoring or project data
Project teams can convert monitoring records containing site coordinates and other attributes into GeoJSON while keeping fields such as status, category, date or responsible office as feature properties.
Prepare data for dashboards
Analysts can convert geocoded CSV data into GeoJSON for dashboards and visualization tools that accept geographic features as an input format.
Check coordinate quality
Plotting the converted coordinates makes it easier to notice invalid values, reversed latitude and longitude fields or points that appear far away from the expected area.
CSV to GeoJSON Coordinate Format
Latitude values should normally be between -90 and 90, while longitude values should be between -180 and 180. GeoJSON stores Point coordinates in longitude, latitude order even when your CSV lists latitude first.
