WKT ↔ GeoJSON Converter
Convert spatial geometry between Well-Known Text (WKT) and GeoJSON. Validate the geometry, preview it on an interactive map, copy the result and download the converted output.
Convert WKT and GeoJSON
Choose a conversion direction, paste geometry and preview the result on the map.
GeoJSON Output
Converted output will appear below.
Map Preview
Supported converted geometry will appear here.
Convert WKT to GeoJSON
Paste WKT geometry such as POINT, LINESTRING or POLYGON and convert it into standard GeoJSON for web maps, APIs and GIS workflows.
Convert GeoJSON to WKT
Paste GeoJSON geometry, Feature or FeatureCollection data and convert supported geometry into Well-Known Text for databases and spatial systems.
Preview Geometry on a Map
Review the converted geometry visually on an interactive map to confirm that points, lines and polygons appear in the expected location.
What are WKT and GeoJSON?
WKT, or Well-Known Text, is a text representation of geometric objects such as points, lines and polygons. GeoJSON is a JSON-based format widely used in web mapping, APIs and GIS applications. Both formats represent spatial geometry, but they are commonly used in different systems and workflows.
How to use the WKT ↔ GeoJSON Converter
- Select the conversion direction.
- Paste WKT or GeoJSON into the input editor.
- Select Convert.
- Review any validation message.
- Inspect the converted geometry on the map.
- Copy or download the converted output.
Common Uses & Real-Life Examples
WKT and GeoJSON often appear in different parts of a spatial data workflow. A converter is useful when moving geometry between GIS, databases, APIs and web mapping tools.
Move geometry from a spatial database to a web map
A developer can convert WKT returned from a spatial database into GeoJSON before displaying the geometry in an online map.
Prepare GeoJSON for database storage
GeoJSON geometry from an API or web application can be converted to WKT for systems that store or exchange geometry in Well-Known Text format.
Check a polygon copied from GIS software
A GIS analyst can paste a WKT polygon, convert it to GeoJSON and quickly preview the shape before using it in another application.
Troubleshoot spatial API responses
Developers working with mapping APIs can convert between the two formats to confirm geometry structure and identify format mismatches during integration.
Convert coordinates for testing
A simple POINT geometry can be converted between formats when testing coordinate handling in GIS, database or web mapping code.
Prepare geometry for data exchange
Teams can convert spatial geometry into the format required by another platform without manually rewriting coordinates.
