How to change ALLCAPS to lowercases but ignore the rest?

[mauve]

How do I only change words that are ALLCAP to lower case, while ignoring everything else like example, Example, ex48ample, ExamPle? thank you

If its always english letters, then RegEx(1) needs a checkmark for "v2", with a "Match" and "Replace" something like...
^([A-Z]+)$
\L$1

im sorry i cant make it work. couldn't find anything

allow me to rephrase, if the "word" has any lowercase or number, leave it be. if the word is allcap [A-Z], then change it to lowercase.

Yes, that is exactly how it conducts.. It will only lowercase names, when ALL of their text is uppercase english letters.
If its not conducting for you, then its probably better to provide some complete now-name ==> new-name examples?

Many apologies, the answer was to lowercase the whole name, when it was all english uppercase letters.
To only lowercase some words inside of the name, the "Match" and "Replace" can be more like...
(^| )([A-Z]+)(?= |$)/g
$1\L$2
