The core WordPerfect Office applications support an impressive range of
file formats, including Open Document Format (ODF), the very oldest
WordPerfect versions, and a few ancient Microsoft Office formats (Word
for DOS, anyone?) that even Microsoft doesn't support anymore. Most
important, WordPerfect Office can open the latest XML file formats from
Office 2007 (those with the -x extensions, like .docx, .xlsx, and
.pptx).
In fact, WordPerfect seems to have an easier time dealing with the new
Microsoft Office file formats than with the traditional ones, and often
imports them with fewer glitches. WordPerfect's compatibility is
extremely good--but not perfect. Most of the Word documents I tested
imported without a hitch, although I had problems with richly formatted
documents, such as missing or mangled pictures. Overall, WordPerfect's
support for Office file formats is good enough that most workers won't
face a headache when exchanging documents with their colleagues.
