XLSM to XPS Converter

The XLSM format is a macro-enabled spreadsheet file created by Microsoft Excel 2007 and later versions, utilizing the Office Open XML (OOXML) standard (ISO/IEC 29500). Unlike the standard XLSX format, XLSM files store embedded macros written in Visual Basic for Applications (VBA), allowing for automation and complex scripting within the workbook. The file structure relies on ZIP compression to contain XML documents for data, styles, and macro binary parts (vbaProject.bin), presenting a security risk that often requires user authorization to execute active content.

XLSM files open natively in Microsoft Excel (2007+) on Windows and macOS, which provides full VBA execution support. For non-Microsoft environments, LibreOffice Calc, OpenOffice Calc, and WPS Office can open these files and view data, though VBA macro execution compatibility varies significantly. Google Sheets can import XLSM data but strips the VBA macros, converting the file to its native format without automation features.

XPS (XML Paper Specification) is a fixed-layout document format developed by Microsoft and later standardized as ECMA-388 (Open XML Paper Specification). It serves as a page description language similar to PDF, utilizing a ZIP-based container to hold XML markup (XAML) for layout, embedded fonts, and vector graphics. The format ensures document fidelity across different printers and displays by defining the precise position of every element on the page.

Windows operating systems (Vista through 10) include a native 'XPS Viewer' application. On Windows 11, this feature is optional and may require manual activation via 'Optional Features'. Non-Windows users must rely on third-party tools like MuPDF or online conversion services to view or convert the content to PDF.
