How to convert KMZ to CSV

  1. Add your KMZ map files

    Drop KMZ files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. CSV is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab.

  3. Download

    Save the CSV, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The KMZ to CSV converter is part of this page and runs inside your browser. Your map files are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

KMZ to CSV: what to expect

KMZ is a compressed archive, so text editors and many scripts cannot read it directly. CSV is plain text that every spreadsheet, database and script can read. KMZ is at home in KML with its icons and overlay images in one file; CSV is the usual choice for moving tabular data between systems.

Every format is read into plain GeoJSON features and written out from there, so coordinates, names and properties carry over wherever the target has a place for them. XML that declares custom entities is refused, and KMZ files are parsed without touching the network. The KML inside the KMZ is read; icons and overlay images in the archive are not carried over. Each point, and each vertex of a line, becomes one row with name, lat and lon columns, plus elevation and time when the data has them. Areas cannot be written as rows, so a file with polygons is refused. Text that starts with =, +, - or @ is escaped so a spreadsheet does not run it as a formula.

KMZ vs CSV

KMZ

KMZ map file

A KMZ is a ZIP archive containing a KML file, normally named doc.kml, and the icons and images it uses. Google Earth saves a placemark collection as KMZ so that the pictures travel with it.

CSV

CSV spreadsheet

CSV is a table written as text: one row per line, values separated by commas. Every spreadsheet and database can import and export it, but it holds one sheet only and no formatting, formulas or data types.

Questions

Are my map files uploaded anywhere?

No. The KMZ to CSV conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting KMZ to CSV?

The values are kept. Anything CSV has no way to express, such as formatting, formulas or nesting, is simplified or left out.

Can I convert several KMZ files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert KMZ to CSV on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the KMZ file, press Convert and save the CSV. There is nothing to install.

Is there a file size limit?

Yes. Files up to 200 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
