What is a XLSM file?
XLSM is a macro-enabled spreadsheet format used by Microsoft Excel. It is based on the Open XML format and supports VBA macros for automating repetitive tasks.
XLSM files are useful in business settings where advanced functionality is needed. Because they can execute code, caution is advised when opening files from untrusted sources.
How to open XLSM files
XLSM files are opened with Microsoft Excel and support embedded VBA macros. LibreOffice Calc also supports viewing and basic editing but may not run macros correctly.
