I am working with a Google Sheet where column A contains a set of values. Every value contains the following string "SAME_WORD LETTER", where LETTER is one of the alphabet letters, like "SAME_WORD A", "SAME_WORD B", "SAME_WORD C", etc. The first letter in SAME_WORD is always capital, the string may be preceded and followed by either a space or a symbol (like a dash) but never by another letter or number.
The following formula does what I need for A, B, and C but it's very long with all the alphabet letters
=ArrayFormula(IF(REGEXMATCH(A:A,"\b SAME_WORD A(.*)"),"SAME_WORD A",IF(REGEXMATCH(A:A,"\b SAME_WORD B(.*)"),"SAME_WORD B",IF(REGEXMATCH(A:A,"\b SAME_WORD C(.*)"),"SAME_WORD C"))))
I would like to improve efficiency and learn something so my request is to modify my formula to remove the conditionals and use something else instead, like REGEXEXTRACT.
