Sorts of XLSX Files


Primary XLSX File Association

.XLSX
File Name:.xlsx
Group:Microsoft Excel Open XML Spreadsheet

Spreadsheets made with the later versions (Office 2007 or above) use this file extension. Older versions (2003 and below) use the .xls file extension but since the newer versions now use the Open XML format, thus the XLSX file extension was created. Microsoft's new technology merges the XML formatting with features such as document compression. This makes the file more manageable on the part of the user.

Troubleshooting Problems Opening XLSX Files


Common Problems Opening XLSX Files

Microsoft Excel Not Present

If you attempt to load your XLSX file, you experience a message such as "Can't Open XLSX Files". When this happens, it is commonly due to Microsoft Excel missing in %%os%%. The typical path of opening your XLSX with a double-click won't work because %%os%% cannot make the program connection.


Tip: If you don't have Microsoft Excel installed, and you know of another program to open your XLSX file, you can try opening it by selecting from the programs listed under "Show Apps".


Incorrect Microsoft Excel Version

In other instances, your Microsoft Excel Open XML Spreadsheet file version may not be supported by your version of Microsoft Excel. Download the latest Microsoft Excel version from the Microsoft Corporation website to ensure you have the correct one installed. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: Investigate your XLSX file by right-clicking and selecting "Properties" to find clues on what version you need.


Conclusion: The majority of XLSX file opening issues are due to not having the correct Microsoft Excel version installed.


Additional XLSX Opening Issues

You can still experience errors opening XLSX files even with the latest version of Microsoft Excel installed on your PC. If you are continuing to have errors with loading XLSX files, other external issues might be to blame. Issues that aren't software-related:

  • XLSX file type Registry entries are wrong
  • Accidental deletion of the description of the XLSX file in the Windows registry
  • Partial installation of Microsoft Excel that did not fully complete
  • Your XLSX can't be loaded properly (file corruption)
  • The XLSX is infected with a virus
  • Hardware related to XLSXs has device driver corruption
  • Your computer does not have the adequate system resources to open the Microsoft Excel Open XML Spreadsheet format
