I can't tell you the number of times I have received raw data from some program or from some person, and the first thing I need to do is remove duplicates from the list. If you find yourself in the same situation, the following macro will be a huge help:
Sub DelDups() Dim rngSrc As Range Dim NumRows As Integer Dim ThisRow As Integer Dim ThatRow As Integer Dim ThisCol As Integer Dim J As Integer, K As Integer Application.ScreenUpdating = False Set rngSrc = ActiveSheet.Range(ActiveWindow.Selection.Address) NumRows = rngSrc.Rows.Count ThisRow = rngSrc.Row ThatRow = ThisRow + NumRows - 1 ThisCol = rngSrc.Column 'Start wiping out duplicates For J = ThisRow To (ThatRow - 1) If Cells(J, ThisCol) > "" Then For K = (J + 1) To ThatRow If Cells(J, ThisCol) = Cells(K, ThisCol) Then Cells(K, ThisCol) = "" End If Next K End If Next J 'Remove cells that are empty For J = ThatRow To ThisRow Step -1 If Cells(J, ThisCol) = "" Then Cells(J, ThisCol).Delete xlShiftUp End If Next J Application.ScreenUpdating = True End Sub
The macro works on a selection you make before calling it. Thus, if you need to remove duplicate cells from the range C15:C59, simply select that range and then run the macro. If you select more than a single column in the range (for instance, C15:E59), then only the first column in the range is affected. When the macro is complete, the duplicate cells are removed, as are any blank cells.
