Convert KMZ to CSV online
Convert zipped KML (KMZ) — the compressed Google Earth format that packs KML plus its assets into one file — into CSV, which is plain spreadsheet rows of latitude/longitude you can open in Excel or Google Sheets. Drop your KMZ 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.
Convert in the cloud
MapGO detects the format and produces your download in seconds.

Why convert KMZ 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.
KMZ vs CSV at a glance
| KMZ | CSV | |
|---|---|---|
| Typical use | Sharing Google Earth maps as a single compressed file | Spreadsheets and data analysis — Excel, Google Sheets, pandas |
| Size on disk | Small — it is a zip archive of KML plus images | Small for point data; geometry beyond points stored as WKT text |
| Attribute support | Same as KML: data lives in ExtendedData | 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 | Needs conversion for web maps | Fine for point data; not a real geometry format |
Other ways to convert KMZ 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 KMZ 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 KMZ to CSV converter free?
Partly. Every new account gets three welcome conversions for free, so you can try KMZ 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.
Do I need to unzip my KMZ first?
No. Upload the .kmz as it is. MapGO opens the KML document inside (doc.kml) and converts it. Icons and images packed in the KMZ are styling, not data, so they are not carried 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.

Open your KMZ in the workspace, check the shapes and attributes, then convert and download from the same place.
