At the moment I only know of questions about interfacing the API of Microsoft office eg using COM technology. This shows that at least some haskellers are interested in office documents. That's why I want to mention www.noooxml.org Summary: Microsoft wants to create a new ISO standard for its OOXML format which you will never be able to implement completely. It's also about 6000 pages compared to 600 pages (ODT, OpenOffice is using this) Most haskell libraries are kind of open source. If tey weren't haskell wouldn't be that appealing.
