Just add a count column next to your list in Excel with the formula:

=COUNTIF(A:A,A2)

Open in new window

Then apply filters and select only 1 in the count column:

Dim Rw As Double, WS As Worksheet

Sub Keep_Unique()

    Set WS = Sheets("Sheet1")
    
    Rw = WS.Cells(Rows.Count, 1).End(xlUp).Row

    WS.Cells(1, 1).Value = "Values"
    WS.Range(WS.Cells(2, 2), WS.Cells(Rw, 2)).FormulaR1C1 "=IF(OR(RC[-1]=R[-1]C[-1],RC[-1]=R[1]C[-1]),1,0)"
    WS.Range(WS.Cells(1, 1), WS.Cells(1, 2)).AutoFilter Field:=2, Criteria1:=1
    WS.Range(WS.Cells(2, 1), WS.Cells(Rw, 2)).SpecialCells(xlCellTypeVisible).EntireRow.Delete
    WS.Range(WS.Cells(1, 1), WS.Cells(Rw, 2)).AutoFilter
    WS.Columns(2).Delete
    
End Sub

Open in new window

End Sub

    WS.Cells(1, 1).Value = "Values"

    WS.Range(WS.Cells(2, 1), WS.Cells(Rw, 2)).SpecialCells(xlCellTypeVisible).EntireRow.Delete
    WS.Range(WS.Cells(1, 1), WS.Cells(Rw, 2)).AutoFilter
    WS.Columns(2).Delete
    
End Sub

Open in new window

Forgot the line to properly sort

bearblack, does OO really support VBA? Now I have to go look...

I am assuming OO does not have the remove duplicates feature like Excel 2007 has.

Looks like it's got something, which is described here:

Sorry -- Missed the OO part thanks for the catch
