IMPLEMENTATION

Viewers responsible for this format

XLSM uses the Open XML workbook package while allowing a VBA project to be embedded. Anyfile reads supported sheets with SheetJS and deliberately treats macro code as inactive package content.

Common question

Is it safe to open an XLSM here?

The viewer parses workbook data locally and does not execute the embedded VBA project, though malformed files can still be rejected.
