Using Find and Replace to switch the All Caps text with the lowercase text

Hi, I'm using a Mac with Microsoft Word, and sometimes things go wrong with Find and Replace. I'm trying to switch the positions of the all-caps text and the lowercase text in a list of items (sample pasted below). Since I can't figure out a macro to make that possible, I've tried to get Find and Replace to highlight the all-caps text so that I can cut it and then paste it into a new column. Unfortunately, nothing happens when I tell the app to find the all-caps text. Maybe I just need to somehow make a macro?
