GeoJSON to WKT

WKT (Well-Known Text) is the textual notation for geometries used by spatial databases (PostGIS, SpatiaLite), desktop GIS (QGIS) and the OGC standard. If you want to take points, lines or areas from a GeoJSON file into a database column, a SQL query or a GIS tool, you need them as WKT. This tool reads your GeoJSON and writes one WKT line per geometry.

All common geometries are supported: POINT, LINESTRING, POLYGON (with holes), MULTIPOINT, MULTILINESTRING, MULTIPOLYGON and GEOMETRYCOLLECTION. The coordinate order is longitude then latitude in both formats, so nothing is swapped. A third coordinate (elevation) is written as WKT with the Z tag. A FeatureCollection yields one WKT geometry per line.

Everything runs entirely locally in the browser - your possibly sensitive location data never leaves your device. Honestly framed: WKT stores pure geometry. Properties such as name or description have no place in WKT and are not written out; if you need attributes, GeoJSON, KML or GPX are a better fit. Invalid GeoJSON is rejected with a clear message.

Specifications

In 3 steps

1. Drop your GeoJSON file.
2. The conversion runs automatically.
3. Download the WKT (e.g. for PostGIS).

Limitations: Converts GeoJSON (FeatureCollection, Feature or a bare geometry) to WKT: POINT, LINESTRING, POLYGON with holes, multi variants and GEOMETRYCOLLECTION; one line per geometry. Elevation as the Z tag. WKT stores geometry only - properties (name/description) are not carried over. Coordinates WGS84 (longitude, latitude). Invalid GeoJSON is rejected with a clear error.
