About CSV

Comma-Separated Values (CSV) files store tabular data with coordinate columns (latitude/longitude or WKT geometry). A simple, universal format supported by virtually all data tools.

Extensions: .csv
Software: Excel, Google Sheets, QGIS, Python/Pandas, R
Limitations: No built-in geometry type — requires coordinate columns. No CRS metadata. No support for complex geometries without WKT.

About KMZ

KMZ is a compressed (zipped) version of KML files. It packages the KML document along with any referenced images, icons, or overlays into a single archive.

Extensions: .kmz
Software: Google Earth, Google Maps, QGIS, ArcGIS
Limitations: Same as KML (WGS 84 only). Requires extraction to edit the underlying KML.
