Regex Match only a Word or Words in ALL CAPS and nothing else

Question

Help.  My input is Field1.  I want to match words in ALL CAPS.  There can be 1-N words.  I want to ignore lines that might start with an ALL CAPS word or words but that contain other text.

I tried the following expression.  It works, but there is an anomaly.  It captures { -- when it should not.   How can I fix this?

if REGEX_Match([Field1], Uppercase([Field1]),0) then [Field1] else '' endif

Example below.  Note { ends up in New when it should not.

Try using this Regular Expression in your Formula Tool 🙂

"^([A-Z\s]*)"

This expression essentially means, "If the string starts with a capital A-Z, only has capital letters A-Z following it, and has a white space following after, then create a match.".

I've attached my proposed solution to this comment. Please let me know if you need any more help or assistance!
