How to Open a Xlxs File

by Anthony Smith

With the release of Microsoft's Office 2007 Suite, the spreadsheet application Excel began using a new file format with the .xlxs extension. This has presented some confusion and compatibility issues for users of older versions of Excel. While Excel 2007 can open, edit and save files in either the old .xls or the new .xlxs format, older versions cannot open the new files. Follow these steps in order to open these new .xlxs files.

Step 1

Open your web browser and go to the following URL:

Step 2

Download the free 60-day trial version of Microsoft Office Pro 2007, which includes Excel 2007.

Step 3

Follow the onscreen install-wizard instructions to install the software on your computer.

Step 4

Open Microsoft Excel and click on the Office start button in the upper-left corner of the window. From the list of options, select "Open."

Select the xlxs file that you wish to open and click the "open" button at the lower right of the window. Excel 2007 will open the file.


  • The Office trial will open and close up to 25 times before you must activate it with the product key. Get the full 60 days of your free trial by activating your Office Suite. Click on the Office Trial icon with a large green dot, and it will display the Product Key code needed to activate.
