CSV to KML, Explained
A spreadsheet of coordinates, exported from a GPS log, a survey, or a database, is easy to edit but invisible on a map. KML is what Google Earth and Google Maps read instead. Whether you call it a csv to kml converter or a csv kml converter, converting from CSV to KML turns each row into a point you can actually see, placed exactly where its latitude and longitude say.
Why This Converter
Amazing Features, Free
- Auto-detects your columns. lat, latitude, y, lon, lng, long, longitude, x — no exact header names required.
- Keeps every column. Extra fields like category, notes, or ID are kept as data on each point, not dropped.
- Bad rows don't break the file. Rows with missing or invalid coordinates are skipped, and the result tells you how many.
- Sample CSV included. Not sure of the format? Download a working example first.
- Instant stats before download. See the point count the moment it converts.
- Nothing is ever saved. Converted in memory over an encrypted connection and forgotten the moment the response is sent.

Frequently Asked Questions
What does my CSV file need to convert to KML?
A header row plus a latitude column (lat, latitude, or y) and a longitude column (lon, lng, long, longitude, or x) — this csv to kml converter finds them automatically under any of those common names. A name column is optional but recommended.
How do I convert CSV to KML?
Upload your .csv file above and click Convert. Every row with valid coordinates becomes a point placemark in a single ready-to-use KML file.
Is this a free CSV to KML converter?
Yes — this csv kml converter is completely free, no signup, no file limit beyond 5MB, no watermark.
Does it keep my other CSV columns?
Yes. Every column besides latitude and longitude is kept as data attached to each point in the KML, not just the name.
What happens to rows with missing or bad coordinates?
They're skipped automatically rather than failing the whole conversion — the result tells you how many rows were skipped, so nothing silently goes missing.
Do you store the CSV files I upload?
No. Your file is converted entirely in memory on our server, over an encrypted connection, and is never written to disk, logged, or kept after the response is sent.
Can I see an example of the CSV format first?
Yes — use the "Download Sample CSV" button above the upload box for a ready example with the right column headers.
