use conditional formatting for this

You would use the countif worksheet function to determine if there are
duplicates.

Assume your values are all in Col A, select Col A, do Format / Conditional
Formatting / Change 'Cell value' is to 'Formula is' and put in
=AND(A1<"",COUNTIF($A:$A,A1)1) and then hit the format button and choose a red
pattern from the pattern tab.

If data was across Columns A:C then select columns A:C and change formula to:-

=AND(A1<"",COUNTIF($A:$C,A1)1)

If only using a small range then select only that range and ensure that the top
left cell in your range when selected is what goes into the formula where A1
currently is, and the whole range replaces the $A:$C bit.
