Question : Case-insensitive ISNUMBER(lLOOKUP) in Excel

How do I make this formula not case sensitive? I want it to return TRUE if any of the words or phrases in my list 'dingnots' occur in T9, regardless of case.

Thanks,
John

1:	=ISNUMBER(LOOKUP(1024,FIND(dingnots,$T9)))

Answer : Case-insensitive ISNUMBER(lLOOKUP) in Excel

Hello John,

Find() is case-sensitive, Search() is not, but does the same thing.

=ISNUMBER(LOOKUP(1024,SEARCH(dingnots,$T9)))
