How can I convert PDF to Excel Offline?
I'm not aware of any, and, considering the PDF format, it would be virtually impossible to convert any but the simplest (in terms of formatting) PDFs to Excel or Word.

How about trying to use a .xlsx from one of your sites? If that's even possible, one would have to either format the whole document (including all macros and macros of every kind), or just have all the macro's (and everything in the way of text) in it. A quick web search (at least for my area of expertise — HTML — can be done fairly quickly) would have revealed numerous .SLS files, not all of which are available anywhere on the web. If you can't convert them to Excel, maybe you should just go with the WordPress plugin. I think the most likely reason, to my knowledge, no plugin exists for this, is a couple of reasons (and one is that there are no plugins that allow the use of XML in the main framework of WordPress). You are right, if someone was able to find some XML.
