EDDX format is stored in text format using XML.
Edraw Max software comes with a range of export options and it works well in conjunction with Microsoft Office. If you need your projects (.eddx) to be exported as Microsoft Word documents (.doc), you can do that by using the File ► Export & Send ► Office option.
