About XLSX Files

What is an XLSX file?

XLSX is the default file format for Microsoft Excel versions 2007 and later. It's based on the Office Open XML standard and uses ZIP compression to reduce file size. XLSX files can contain worksheets, charts, macros, and other Excel elements.

XLSX vs XLS

Unlike the older XLS format which was a binary file format, XLSX is based on XML and open standards. XLSX files are generally smaller, more efficient, and less prone to corruption than XLS files. They also support more rows and columns per worksheet.
