Office Open XML Converter allows you to convert Open XML files that were created in Office 2008 for Mac so that you can open, edit, and save them in earlier versions of Office for Mac. This application can convert Word documents, Excel workbooks, and PowerPoint presentations.
You can choose to convert and open one file, or convert a large number of files at the same time.
