Try it.

Sub DeleteMatches()
Dim k As Integer
Dim i As Integer
Dim j As Integer
Dim MatchArray()

k = 0
For i = ActiveSheet.Range("B65536").End(xlUp).Row To 2
Step -1
For Each Cell In ActiveSheet.Range("A2:A" &
ActiveSheet.Range("A65536").End(xlUp).Row)
If Cell.Value = ActiveSheet.Cells(i, 2).Value
Then
ActiveSheet.Cells(i, 2).Delete shift:=xlUp
ReDim Preserve MatchArray(j)
MatchArray(j) = Cell.Value
End If
Next Cell
Next i
If Not IsArray(MatchArray) Then
For i = ActiveSheet.Range("A65536").End(xlUp).Row
To 2 Step -1
For j = 0 To UBound(MatchArray)
If ActiveSheet.Cells(i, 1).Value =
MatchArray(j) Then
ActiveSheet.Cells(i, 1).Delete
shift:=xlUp
End If
Next j
Next i
End If

End Sub

Hi,

Does anyone know, or point me in the right direction, how
to have Excel
find duplicate cells and delete them. For example, I
have 2 columns of
numbers. I need Excel to read the first cell in column A
and look for
a match in column B, and if it finds it, delete both.
Then to repeat
for the whole column. Any help would be appreciated.

Thanks,
Marc
