Finding duplicate values, excel

Hi everyone,

I need to find a way to recognize duplicates in a excel spreadsheet.  (Checking specific rows and columns)

For example, if a user has to enter date in A1, B2, C3, and D4 I want to check those columns to see if any of them match.

I am hoping to have something like this in a macro.

Can anyone help me?

You can simply use Conditional Formatting

Highlight Duplicates

Conditional Formatting will be more efficient because you don't need to enable and run macros.

Sorry this should work

This method will be automatic unlike a macro. Even better if you format the data as a Table the formats will expnad as data is added automatically

If you highlight the whole sheet (or the part that will have data) and go to conditional formatting, then select highlight duplicates, a cell will instantly get highlighted when someone enters a duplicate.
