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
