Since the last post, I have ported it to WPF (semi-MVVM) and added support for Excel and PowerPoint files, and custom fields and scripts.
The conversion is done by interop with office. Apparently consistency is too much to ask for from Microsoft, and the libraries for Excel, PowerPoint, and Word are all slightly different. (I've also found that Excel will randomly fail to open/convert a spreadsheet, or randomly display odd windows, progress bars, or enable/disable add-ins. But, I digress.)
Just to get it out of the way (it has been mentioned before), the iTextSharp library is not mine, and so I do not control the naming conventions for it. Please do not suggest to rename any part of that library. I also wish they would properly capitalize their namespaces, but there is nothing I can do.
