Validate and convert CSV files to normalized CSV and GeoJSON files

This tool supports CSV files with separate fields for Latitude and Longitude, using any of the following case-insensitive field names:

• Latitude: lat, Lat, LAT, latitude, Latitude, LATITUDE
• Longitude: lon, Lon, LON, lng, Lng, LNG, long, Long, LONG, longitude, Longitude, LONGITUDE

It also supports CSV files with case-insensitive field names wkt or geometry, containing values of type POINT, LINESTRING, or POLYGON. In that case, check the Enable WKT support checkbox.

By default, the validator:

• Displays invalid rows
• Excludes them from output
• Normalizes and converts the remaining rows into downloadable CSV and GeoJSON files

To display valid rows, check the checkbox at the top of the page. Note: For large files, rendering table rows may be time- and resource-intensive.
