Paste a CSV (or upload) with a WKT column, lon/lat columns, or bbox columns and convert rows to WKT lines. Runs fully in your browser.
FAQ
Which columns are auto-detected?
wkt/geometry/geom, lon/lat (or longitude/latitude), or bbox columns like minx/miny/maxx/maxy.
Header and delimiter?
Toggle header and set delimiter (comma/semicolon/tab) to match your CSV.
Can I include properties per line?
Yes — enable 'Append properties (JSON)' to add a JSON blob after each WKT (tab-separated).
WKT only vs numbered?
Choose WKT-only per line or prefix each line with a row index.
