One way

=SUMPRODUCT(--(EXACT(A2:C2,A2)))=3


where the 3 columns are A, B and C


you can also use this array formula

=AND(EXACT(A2:C2,A2))

entered with ctrl + shift & enter)

I understand that the Exact formula can compare 2 columns. Is there a way
that I can compare 3 columns of data?

Thanks.
