I'm using a version of Word from 2012, and the search results under "turn off word wrap" gives lots of wrapping options but nothing to remove it completely.

That said, you can copy the text in the Word document into a Notepad text file (Notepad is an accessory in Windows - depending on your version of Windows you may have to poke around in Microsoft Office files to find it). In Notepad you can go to the top menu option "Format" and deselect "word wrap." It really is that simple. Then "Control A" to select all and past it in here, where it will wrap according to the width of the window. I've used this over the years for pasting lots of things into mudcat screens.
