More info
An XLSM file contains not only table cell values but also formatting instructions, formulas, graphics and macros. They are xlsx files with macros. The included macros or scripts may contain malicious code, so you should do a virus check before running it and always install the latest security updates for Microsoft Office.
XLSM is an XML based file format (Office Open XML) that is not legible with older versions of Excel. For the Office versions 2000, 2003 and XP, this functionality can be used with the help of the Microsoft Office Compatibility Pack, whereby the result of an imported XLSM file does not always have to correspond to 100% of the original. There may also be restrictions when processing the macros.
Office Open XML is an open Bro Bro applications standard developed by Microsoft to provide file sharing between different Office suites.
An XLSM file consists of several XML files, which are automatically compressed into an archive when saved using the ZIP algorithm. This saves space compared to the old format. Other benefits include better data integrity and easier data recovery in case of data loss.
