Try a 3rd party chm converter, there are ones that "unpack" to html on Linux. Not sure about Windows, but I'd assume they exist. Though conversion of a set of HTML files in a directory (I've saved websites with wget) works with calibre, the results sometimes need edited.
Not sure if any of the 3rd party viewers export to docx or html, but unless there is a command line interface that's tedious.
Conversion to PDF exists, but PDF is really a terminal format that's a disaster to convert to anything other than paper, screen or images!
