My primary desktop is Linux, so I’m an OpenOffice user. At home, I run NeoOffice on the Mac. You can just imaging that special feeling I had when I started seeing e-mail attachments with file extensions like .docx, .pptx and .xlsx! These new XML-based file formats are associated with Microsoft Office 2007 and do not (yet) work with OpenOffice or NeoOffice.
I used a free on-line service called Zamzar to convert the Office files to the more familiar .ods (spreadsheet), .odp (presentation) and .odt (word processing) formats. It worked perfectly. Submit you file and you will be notified via e-mail when it is ready to pick up the converted form.
Very cool find! Thanks Mark!
FYI, OpenOffice 3.0 Beta has MS Office 2007 import filters
Ola:) nice article, and I have one tip. At file-extensions.org I found very nice and detailed informations about docx, pptx, xlsx, ods, odp, odt and other document formats.
