Convert KML to CSV online
Convert Keyhole Markup Language (KML) — the Google Earth and Google Maps format — into CSV, which is plain spreadsheet rows of latitude/longitude you can open in Excel or Google Sheets. Drop your KML file below, CSV is already selected as the output, and download the result. Everything runs in your browser and the cloud; you never install anything.
Upload your file
Drag and drop it into the converter below. A free account comes with three welcome conversions.

Why convert KML to CSV with MapGO?
Most online converters take one file and hand back one file. MapGO is built on a real geospatial engine, so a single upload can do more.
- Several outputs in one upload
Tick CSV and any other formats you need; every selected format is delivered from the same file.
- Files up to 5 GB
Far beyond the browser-based converters that choke past a few hundred megabytes.
- Reproject while you convert
Set a source and target EPSG code and the coordinate system is changed during the conversion, no second tool needed.
- Private by default
Files are deleted automatically after 48 hours.
KML vs CSV at a glance
| KML | CSV | |
|---|---|---|
| Typical use | Google Earth / Google My Maps visualisation and sharing placemarks | Spreadsheets and data analysis — Excel, Google Sheets, pandas |
| Size on disk | Verbose XML; the zipped KMZ variant shrinks it considerably | Small for point data; geometry beyond points stored as WKT text |
| Attribute support | Styling-first — data lives in ExtendedData and is easy to lose | Flat columns only — no nesting; readers guess the types |
| Software support | Google Earth/Maps and most GIS tools | Opens everywhere, including every non-GIS tool |
| Web-friendliness | Good inside the Google ecosystem; niche elsewhere | Fine for point data; not a real geometry format |
Other ways to convert KML to CSV
You don't need an online tool for this. If you have GDAL installed, one command does it.
In QGIS (free): open your KML via Layer → Add Layer, then right-click the layer → Export → Save Features As… and pick CSV as the format.
The MapGO converter above is for when you don't want to install anything, need to convert to several formats at once, or are handling files too large for a desktop machine.

Is the KML to CSV converter free?
Partly. Every new account gets three welcome conversions for free, so you can try KML to CSV without paying. After that, you can either buy a credit pack and pay per conversion, or take a subscription, which gives you unlimited conversions within the plan's file-size limit. There is nothing to install; the whole conversion runs in the cloud.
Is my data kept private?
Conversion is fully automated and your file is never shared. Files are deleted automatically after 48 hours. Download your CSV result and it's yours to keep.
What does the CSV output contain?
You get a clean CSV file with your geometry and attributes preserved, ready to open in the tools that read CSV.
What happens to the attributes stored in my KML?
KML keeps attribute data in ExtendedData elements (and sometimes in free-text descriptions). Structured ExtendedData fields are mapped to real attribute columns in the output; icons and styling are display settings rather than data, so they don’t carry over.
How is geometry stored in the CSV output?
Point layers get plain lat and lng columns next to your attributes — ready for Excel, Google Sheets or pandas. Lines and polygons are written to a geometry_wkt column in standard Well-Known Text, which GIS tools can parse back into shapes.
Can I convert CSV back to KML?
Yes — use our CSV to KML converter for the reverse direction. MapGO supports conversions in both directions between these formats.
