KMZ to CSV Converter — free & private
Upload KMZ (or paste base64) and export a CSV with geometry metadata (WKT, area, centroid, bbox, topology) and flattened properties. Runs fully in your browser — no server uploads.
FAQ
Is my KMZ uploaded?
No — everything runs locally in your browser (no server uploads).
What KMZ structure do you support?
We look for doc.kml first, otherwise the first .kml inside the KMZ.
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, plus one column per property key found in the features.
Are area/centroid values accurate everywhere?
They’re computed directly from the parsed 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.
