Convert KMZ to CSV Online — Free & Instant
Extracting KMZ placemark data to CSV lets you work with Google Earth data in Excel, Google Sheets, or any data analysis tool. Maparz decompresses the KMZ, extracts the KML, and produces a CSV with X (longitude) and Y (latitude) columns alongside all placemark attributes.

About KMZ
KMZ is a ZIP-compressed version of a KML file. It typically contains a doc.kml file at its root along with any referenced images, icons, or overlays. KMZ files are smaller than their KML counterparts, making them easier to share by email or embed on web pages. They are supported by Google Earth, QGIS, ArcGIS, and many online mapping tools. KMZ files can be uploaded directly to Google My Maps.
Strengths
- +Smaller than raw KML
- +Can bundle images and overlays
- +Widely accepted by mapping tools
About CSV
CSV (Comma-Separated Values) files containing geometry data typically include latitude and longitude columns (or X/Y columns for projected data). Many data providers distribute point datasets as CSV because they are easy to open in Excel, Python, and R. When converting from a vector format to CSV, Maparz outputs an X (longitude) and Y (latitude) column along with all attribute data. To convert CSV to GeoJSON, your file must have columns identifiable as longitude (x, lon, lng, longitude) and latitude (y, lat, latitude).
Strengths
- +Opens in Excel, Google Sheets, any spreadsheet
- +Human-readable and editable
- +Lightweight for point data
Frequently asked questions
Q.Is this the same as exporting from Google Earth?
Similar. Google Earth's built-in CSV export is limited. Maparz preserves all placemark attributes including custom fields not visible in Google Earth's export.
Q.Does CSV handle polygon KMZ data well?
CSV is best for point data. For KMZ containing polygons or lines, GeoJSON or Shapefile will better preserve the full geometry.
