.xlsx file extension
- Microsoft Excel (XML) Spreadsheet file.
A .xlsx file is a saved Excel spreadsheet file, generated with Microsoft Excel 2007 (or later) that is saved in XML format. A .xlsx file does not contain any macros (VBA), to have a macro-enabled spreadsheet the spreadsheet must be saved as a .xlsm file.
The file is actually a set of XML files that are compressed. The individual XML files can be viewed by renaming the .xlsx file to .zip and treating it as a .zip file.
It is possible to open .xlsx files using earlier versions of Microsoft Excel, but to do this you need the Microsoft Office Compatibility Pack. The Microsoft Office Compatibility pack is available from www.microsoft.com/downloads/details.aspx?FamilyId=941B3470-3AE9-4AEE-8F43-C6BB74CD1466&displaylang=en.
