You can do this with formulas and a helper column using:
=IF(B1=A1,"",B1)
Then copy down, highlight all formulas, copy, paste special > values.
Or easier, you can just run a macro:
Sub Delete_ColB()
Dim i As Integer
For i = 1 To Cells.SpecialCells(xlCellTypeLastCell).Row
If Cells(i, 2) = Cells(i, 1) Then Cells(i, 2) = ""
Next
End Sub
> I want to copy date from one worksheet into another with copy past special as
> a "value" from two columns. However if the department is the same in cell B1
> as A1 I want B1 to be blank. Is there any one of doing this?
