Suppose I have data in A2, C2, and E2. And in column F2 i want to show that if any of those three separate cells (it is not a range) have duplicate data horizontally (in a row), then show in F2 "duplicate" if not then show "safe".

How would I do that efficiently without repetitive formula or multiple nested IF functions?

Sorry Forgot to mention that in this case the context given is that A2, C2 and E2 must have data and none of them is blank or "-".

Maybe...

=IF(OR(A2=C2,A2=E2,C2=E2),"Duplicate","Safe")

And what if suppose I wanted to change the condition that the A2 contains data, C2="-", and E2="-", with what formula can I use to verify that the data in A2 is not duplicated in C2 or E2, while ignoring the fact that there is a duplicate of E2=C2="-" ? With what formula could i do that?

Not sure i understand what you need. See if this works

=IF(SUMPRODUCT(--(COUNTIF(A2:E2,A2:E2)*(MOD(COLUMN(A2:E2)-COLUMN(A2)+1,2)=1)*(A2:E2<>"-")>1)),"Duplicate","Safe")

hmm...my formula in post 5 has a flaw

Try this new version
=IF(OR(AND(A2<>"",A2<>"-",A2=C2),AND(A2<>"",A2<>"-",A2=E2),AND(C2<>"",C2<>"-",C2=E2)),"Duplicate","Safe")

Let me clarify then, supposed i have the following table:

[TABLE="width: 598"]

The formula should be able to exclude the fact that in each row "-" is duplicate and should not include cell of column B, D and F (it should not use a range) in the formula.

Doesn't Marcelo's post 6 formula meet the requirement?

Can any of your rows have 3 numbers in the relevant columns?

I didn't notice post #6 sorry. Yes it did solved my problem.

Yes it can have 3 or more or less than that and it doesn't have to be numbers, would you explain why did you ask ?
