CSV to GeoJSON Converter

Convert CSV or TSV latitude and longitude columns into a GeoJSON FeatureCollection with a local coordinate plot.

CSV coordinates to GeoJSON

Use a header row and WGS84 decimal degrees: latitude −90 to 90, longitude −180 to 180. Maximum 2 MiB, 5,000 data rows, and 100 columns. Quoted fields and multiline values are supported.

CSV data and coordinates are processed in this browser. They are not uploaded, included in tool analytics, or sent to a map service; no map tiles are loaded.

How to convert CSV coordinates to GeoJSON

  1. Paste CSV/TSV with a header, or open a UTF-8 CSV/TSV file. Select the correct separator.
  2. Confirm which columns contain WGS84 decimal latitude and longitude. Convert DMS values to decimal degrees first.
  3. Generate GeoJSON. Correct every reported invalid row before exporting.
  4. Inspect the coordinate plot and point table, then copy or download the complete .geojson FeatureCollection.

CSV coordinate examples

  • A row named Taipei 101 with latitude 25.033 and longitude 121.5654 produces coordinates [121.5654, 25.033]. Its name remains a string property.
  • A row with longitude −74.006 and latitude 40.7128 produces coordinates [−74.006, 40.7128]. Other columns such as id, category, or a quoted description remain string properties.

Frequently asked questions

What GeoJSON does this tool generate?

An RFC 7946-style FeatureCollection containing one Point Feature per valid data row, using WGS84 decimal longitude followed by latitude. Latitude and longitude columns are excluded from properties; other columns remain strings.

Are invalid rows skipped?

No. Any invalid coordinate or mismatched cell count blocks the entire export. The tool shows valid and invalid row counts and the first 20 errors.

Is the preview a map?

It is a longitude/latitude coordinate plot with fixed global axes and no basemap. It does not show roads, calculate distances, transform coordinate systems, or load external map tiles. At most 500 points are drawn; the table and export retain all points.

Your CSV file and coordinate values stay in your browser for this conversion. The tool does not upload them or send them to analytics or third-party map services. Standard site ads and analytics may still load separately.
