About the CSV to GeoJSON Converter

Shops, sensors, survey results, delivery stops — anything with a latitude and a longitude usually lives in a spreadsheet, and every mapping tool worth using wants GeoJSON. Writing that by hand means nesting each row inside a Feature and getting the coordinate order right, which is where most people put their points in the sea.

Paste the CSV and the latitude and longitude columns are found automatically, whatever they are called — lat, Latitude, Y, lng, long. Every other column travels with the point as a property, numbers and true/false can be read as real types, and coordinates can be rounded to a sensible precision. Rows with a missing or impossible coordinate are skipped and listed rather than silently dropped, and the bounding box is shown so you can tell at a glance whether the points landed where you expected.

Frequently asked questions

That is 0,0 — the sign of a missing coordinate, or of latitude and longitude being swapped. Rows with no usable coordinate are skipped here, and the bounding box makes a swap obvious.
