Frequently asked questions

What does my CSV need?

A header row with latitude and longitude columns — recognised names include lat/latitude/y and lon/lng/longitude/x. Any other columns become feature properties.

How are lines and polygons exported to CSV?

CSV is point-based, so non-point geometries are exported using their centroid.

Can I convert Shapefiles?

Not yet — Shapefile (.shp) support is planned. For now use GeoJSON, KML, GPX or CSV.

Is my file uploaded to a server?

No. Conversion happens entirely in your browser; files never leave your device.
