Why Convert XLSX to GZ file?

GZ is a compressed format created with gzip, common on Linux, web servers, and in development. Converting XLSX to GZ compresses your Excel spreadsheet into a gzip archive, useful when a system or workflow specifically expects a gzip-compressed file, and because spreadsheet data compresses well, it can shrink the file noticeably.

This is aimed at technical and Linux-oriented workflows rather than everyday use. Decompressing the GZ restores the original XLSX exactly. For general sharing and broad compatibility, a plain XLSX or a ZIP archive is more practical, so use those for regular needs. Reach for GZ only when a specific system or workflow requires it.
