What Convert CSV to GeoJSON can do:

Convert CSV to GeoJSON transforms structured CSV data into geographic point features for use with maps, GIS tools, and APIs. You just tell it which columns contain coordinates and it does the rest building proper GeoJSON structure while preserving other row data as properties. No complex setup, just paste and go.

Example:

CSV Input:

name,lat,lon
Park,40.7128,-74.0060
Museum,34.0522,-118.2437
Cafe,51.5074,-0.1278

GeoJSON Output:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": { "type": "Point", "coordinates": [-74.006, 40.7128] },
      "properties": { "name": "Park" }
    },
    ...
  ]
}

Common Use Cases:

Convert CSV to GeoJSON is ideal for preparing location-based data for Leaflet, Mapbox, OpenLayers, or custom web maps. It’s also useful for visualizing survey data, asset tracking, or transforming spreadsheet exports into spatial datasets.

Useful Tools & Suggestions:

If your CSV has coordinates, use Analyze CSV to make sure lat/lon columns are clean. And once it’s in GeoJSON, Convert GeoJSON to CSV lets you bring it back for editing anytime.
