Techopedia Explains Office Open XML (OOXML)
Office Open XML is different from Open Office XML, and in many ways they are competing XML standards. The new format can be accessed and worked upon by any application supported by XML, and as such the application need not be part of any Microsoft product or even the Microsoft Office system. Like the binary office file format, Office Open XML formats are also saved in a single container, however they can provide information on components that provide access to the structure which composes the file.
