WKT to CSV Converter — free & private
Paste WKT or GeoJSON, and export a CSV with geometry metadata (WKT, area, centroid, bbox, topology) plus a label column. Runs fully in your browser — no uploads.
FAQ
Is my data uploaded?
No — everything runs locally in your browser (no server uploads).
What columns does the CSV contain?
id, geometry_type, wkt, area_m2, area_km2, centroid_lon, centroid_lat, bbox_minx, bbox_miny, bbox_maxx, bbox_maxy, parts, holes, vertices, label.
Are area/centroid values accurate everywhere?
They’re computed directly from the input coordinates as-is (no CRS detection). If your data isn’t WGS84 lon/lat (EPSG:4326) or has an unusual CRS, results may be off.
Can I export only selected geometries?
Yes — use the centroid-only option or hide the WKT column depending on your workflow.
