If you've been gnashing your teeth as more and more Office 2007 files come your way from your innocent, early-adopter Windows colleagues and friends, time to quit your gnashing. Microsoft's beta of the mellifluously named Microsoft Office Open XML File Format Converter for Mac can now be downloaded from the big M's website. This initial version of the standalone converter tool supports Word 2007 files and is one-way: the resulting RTF output can be resaved as Office 2004 .doc files, but not as Office 2007 .docx files. Support for the newfangled PowerPoint and Excel document formats will be coming later this summer.
As previously noted, the final integrated format conversion bundle that will live inside Office 2004 will not ship until after Mac Office 2008 hits the street. So it goes.
