Office 2007 to Office 97-2003 file conversion

It happened to my friend long back when cracked Microsoft Office 2007 had been successfully installed. Now it happened also to me. Nothing serious, I liked the style Office 2007 gives and enjoyed creating a excel document which I needed to show in my office in xlsx format mistakenly and ended in trouble when I had to open it in my office with older Office version. After little bit googling this one I found out. Just a small exe provided by Microsoft which will convert Office 2007 word, excel and powerpoint files to Office 2003 format.
Here is the link for that.
