Thanks Domenic. This worked well. The first answer was too difficult
because I have a few thousand entries to sort through but your formula worked
well.
helper column>this formula copied down>filter on result>copy
=MOD(ROW(1:1),2)=0
or adapt this
Sub SelectEveryOtherRow()
Dim rng1 As Range
Dim rng2 As Range
For Each r In Range("a1:a21")
If r.Row Mod 2 = 1 Then
If rng2 Is Nothing Then
Set rng2 = rng1
Else
Set rng2 = Union(rng2, rng1)
End If
Set rng1 = r
End If
Next
rng2.Copy Range("g1")
End Sub
