Taking a plain C++ Program into Unreal

I encountered a problem when trying to import the table through the UE editor(not sure what exactly it didn’t like about it, 0,0 was blank and then I had the rows as 1-99, and columns as 1-99. So for right now I’m working on creating a static library so I can call the functions and just create the array in unreal and then access it. And theres another thing, how do I take my C++ class and use and abuse it with the blueprint functions?

Oof, the library is completed, but I’m still having quite a bit of trouble connecting it to the project, going to attempt just adding in the code itself(its only 600 lines) in the project, and then have it create an array of map objects to pull data from. At some point I found a place to just add in code to the project, but I’ve forgotten where, shouldn’t be too hard to find again however.
