what do you define as a dupe?

- any individual cell that is replicated
- matching an entire row
- matching an entire column (D and F)

My addin will handle the first two, not the last

And do you specifically want code that you can see (the addin is code), and if so why - for you to modify?

matching an entire column (A,B,C,D,E and F) (not rows)

Sample attached

The code runs on a user prompted range, the default being the current selection

While the code could be a litlte shorter I have used arrays for a speed gain over range looops

This line is to show thecolumn(s) contents removed
you can take it out
.Interior.Color = vbYellow


Sub DupSel()
    Dim rng1 As Range
    Dim rng2 As Range
    Dim X
    Dim lcol As Long
    Dim lrow As Long
    Dim strTmp
    Dim objDic
    Set objDic = CreateObject("scripting.dictionary")
    Set rng1 = Application.InputBox("Please select range", , Selection.Address, , , , , 8)
    X = rng1
    For lcol = 1 To UBound(X, 2)
        strTmp = vbNullString
        For lrow = 1 To UBound(X, 1)
            strTmp = strTmp & X(lrow, lcol)
        Next lrow
        If Not objDic.exists(strTmp) Then
            objDic.Add strTmp, 1
            If Not rng2 Is Nothing Then
                Set rng2 = Union(rng2, rng1.Cells(1).Offset(0, lcol - 1).Resize(lrow - 1, 1))
                Set rng2 = rng1.Cells(1).Offset(0, lcol - 1).Resize(lrow - 1, 1)
            End If
        End If
    Next lcol
    If Not rng2 Is Nothing Then
        With rng2
            .Interior.Color = vbYellow
        End With
    End If
End Sub
