odf-converter-integrator is an easy way to open Microsoft Office 2007 files (also called Office Open XML, .docx, .xlsx, and .pptx) with a high-quality conversion on any Linux or Windows system in any OpenOffice.org.
odf-converter-integrator uses the high-quality odf-converter code (which converts between Office Open XML and OpenDocument) as packaged by Novell and integrates it into the operating system. That means when you click on a .docx/.xlsx/.pptx file on a web page, in an email attachment, or your desktop, odf-converter-integrator springs into action, converts the .docx/.xlsx/.pptx to an .odt/.ods/.odp, and then automatically opens the new document in OpenOffice.org, StarOffice, Abiword, KWord, Gnumeric, Microsoft Office 2003, or whatever is your default ODF editor.
odf-converter-integrator is simply a little glue to overcome the integration limitation of the Novell odf-converter, which cannot integrate into most editions of OpenOffice.org (such as the vanilla/Sun Microsystems edition, Fedora, OxygenOffice, and others).
Out of the box OpenOffice.org version 3 opens Microsoft Office 2007 documents, but often odf-converter-integrator converts with better quality. See the article "A better .docx converter" for details.
On Ubuntu, odf-converter-integrator works even better: the integration is more seamless, and it saves in Microsoft Office formats with high quality too!
If you use the edition of OpenOffice.org that came with Ubuntu (most common), install odf-converter-integrator chocolate edition. If you downloaded and installed the vanilla OpenOffice.org from the OpenOffice.org web site (less common), then install the strawberry edition.
