| Description | XLSM is the file extension that is assigned to spreadsheets created by Microsoft Excel 2007 and newer. They are saved using the Open XML standard. Just like older version of the Excel spreadsheet, XLSM files can contain tables and worksheets. On top, XLSM files are macro-enabled. They can contain embedded macros that use VBA. | The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. |
| Technical details | As stated above, XLSM files are macro-enabled. This distinguishes the format from XLSX files that are also created by Microsoft Excel. Thus, for Excel to be able to execute the macros embedded in the file, the spreadsheet has to be saved in the XSLM format rather than as a XLSX file. Predecessors of Microsoft Excel 2007 are only able to open XLSM files if they support Open XML components. | The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate. |
