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.

About XLSX

XLSX is the Microsoft Excel Open XML spreadsheet format. When it contains coordinate columns, it can be used as a source for geographic point data.

Extensions: .xlsx

Software: Microsoft Excel, Google Sheets, LibreOffice Calc, QGIS, Python/openpyxl

Limitations: No built-in geometry type — requires coordinate columns. No CRS metadata. Limited to tabular point data.
