How to open docx files without Office 2007
Nov 23rd, 2007 by Jason

Microsoft has introduced a new file format called the Microsoft Open Office XML Format (.docx) with their latest office suite, Office 2007.
But most people are still using Office 2003. The big problem is that this new format is incompatible with older Microsoft Office versions or any other Office alternatives such as Open Office or Lotus, StarOffice, NeoOffice. Before anyone blame Microsoft, they have already created a program called Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. After you’ve downloaded this program, you can easily convert new Office format such as .docx to old Office format .doc and vice versa.
Or if you don’t want to install any program, you can try .docx online converter. Hope this advice help your incompatibility headache.
Mac and P.C. users that do not own Microsoft Office or users of earlier versions of Microsoft Office that are not covered by Microsoft compatibility pack, but still want to convert, open and use Word 2007 DOCX or Excel 2007 XLSX files on their own computer and not email the files to be converted, can use docxconverter.
