About XLSM Files
XLSM is a macro-enabled Excel workbook - a standard XLSX file that also contains VBA macros. Our viewer opens the workbook and displays all of its sheet data safely, without running any of the embedded macros, so there is no security risk in taking a look.
Use this free XLSM viewer to open a macro-enabled Excel file online and read its contents in your browser. Nothing is uploaded and no code executes. If you want a macro-free copy afterwards, our Excel Macro Remover strips the VBA and saves a clean .xlsx.
