CSV to KML Converter — free & private
Paste a CSV (or upload) with a WKT column, lon/lat columns, or bbox columns and convert rows to KML. Runs fully in your browser.
FAQ
Is my CSV uploaded anywhere?
No. Parsing and KML generation run locally in your browser. Your data stays on your device.
What geometry inputs does this support?
Auto-detects one of: a WKT column (wkt/geometry/geom/the_geom), longitude + latitude columns (Points), or bbox columns (minx/miny/maxx/maxy) that become rectangle Polygons.
Which column names are auto-detected?
WKT: wkt, geometry, geom, the_geom. Lon/lat: lon/longitude/x/lng and lat/latitude/y. BBox: minx/miny/maxx/maxy, xmin/ymin/xmax/ymax, or west/south/east/north.
Does this reproject coordinates?
No. KML expects lon/lat (WGS84 / EPSG:4326). If your data is in meters / a projected CRS, reproject first.
Why are some rows skipped?
Rows are skipped when geometry cannot be built (missing lon/lat, incomplete bbox, or empty/invalid WKT).
Why does it say the export is limited?
Row limiting is enabled by default (5000 rows) to keep the browser responsive. Disable it to export everything, but huge CSVs can freeze the tab.
