For the macro to work correctly, make sure both of the following conditions have been met:
- The column in which you want to find duplicates has been sorted based on values in that column.
- The first cell in the column in which you want to find duplicates is selected.
Sample Visual Basic Code
Sub FindDups () ' ' NOTE: You must select the first cell in the column and ' make sure that the column is sorted before running this macro ' ScreenUpdating = False FirstItem = ActiveCell.Value SecondItem = ActiveCell.Offset(1, 0).Value Offsetcount = 1 Do While ActiveCell <> "" If FirstItem = SecondItem Then ActiveCell.Offset(Offsetcount,0).Interior.Color = RGB(255,0,0) Offsetcount = Offsetcount + 1 SecondItem = ActiveCell.Offset(Offsetcount, 0).Value Else ActiveCell.Offset(Offsetcount, 0).Select FirstItem = ActiveCell.Value SecondItem = ActiveCell.Offset(1,0).Value Offsetcount = 1 End If Loop ScreenUpdating = TrueEnd Sub
