XLSX files are the default file format for Excel 2007 and later, while XLS is the default file format for older versions of Excel.

XLSX files can store a variety of data, including numbers, text, formulas, charts, and graphs. They can also be used to create macros, which are automated tasks that can be performed on spreadsheets.

XLSX files are compatible with a wide range of software, including Google Sheets, LibreOffice Calc, and OpenOffice Calc. This makes them a good choice for sharing spreadsheets with colleagues and collaborators.
