(SOLVED) Change ALL CAPS words from in string into Title Case

I've been working on a major project and I'm almost there. Thanks for anyone on the forum who has helped!

This is a case question which no Proper function or anything has been able to solve.

I have strings of of 1+ sentences with some words being in ALL CAPS, and others in Title caps. I want to turn the words in all caps into title caps.

Example: The lazy Fox Jumped OVER the fence.
Output: The lazy Fox Jumped Over the fence.

I've browsed and have been unable to find anything so far. Thanks in advance.
