What does the converter extract?

For each Placemark it pulls the name, description, the parent folder name, and the Point coordinates split into separate latitude, longitude, and altitude columns. KML stores coordinates as lon,lat,alt and the tool re-orders them to the familiar lat,lon layout.

Does it handle nested folders?

Yes. The tool walks up the XML tree from each Placemark to find its nearest enclosing Folder and records that name in the folder column, so you keep the original grouping when a KML organises places into folders.

What about MultiGeometry placemarks?

A Placemark that contains several Point geometries, or a coordinates element with multiple tuples, produces one CSV row per point. The name and description are repeated on each row so every coordinate is captured.

Are LineStrings and Polygons exported?

This tool focuses on point data. It reads every coordinates element, so the vertices of lines and polygons are emitted too, but it does not reconstruct the line or polygon geometry — each vertex becomes its own row.

Is my KML uploaded anywhere?

No. Parsing uses the browser's built-in DOMParser and everything runs locally. Your KML never leaves your device, so it is safe for private or proprietary location data.

KML to CSV Converter

A KML to CSV converter flattens a Google Earth file back into a spreadsheet. KML stores locations as XML Placemark elements with nested folders and longitude,latitude,altitude coordinate tuples, which is hard to read in a text editor. This tool extracts the names, descriptions, folders, and coordinates into clean CSV rows you can open in Excel, Google Sheets, or any analytics tool — all in your browser.

How it works

The converter parses your KML with the browser’s native DOMParser, which validates that the XML is well-formed. It then iterates over every Placemark element. For each one it reads the direct child name and description, and walks up the parent chain to find the nearest enclosing Folder so the original grouping is preserved.

Coordinates live inside one or more coordinates elements. A single element can hold many whitespace-separated tuples, and each tuple is longitude,latitude with an optional altitude. The tool splits these correctly, swaps the order to the more familiar latitude, longitude, and emits one CSV row per point. That means a MultiGeometry placemark or a polygon’s vertex list produces multiple rows rather than being silently dropped.

Output and notes

The CSV header is name, folder, lat, lon, alt, description (the folder column is optional). Any cell containing a comma, quote, or newline is wrapped in double quotes with internal quotes doubled, following RFC 4180, so the file imports cleanly. Because the parsing happens entirely client-side, the tool works offline and never transmits your location data.
