Answer 1

This is a simple example in VBA. It is intended to show the concept, not the best practices. Please use it to get you started, and get back here if you need more help, if you want to improve the performances, etc.

The example assumes that the two lists are in A1:An and B1:Bm, and the resulting list goes in column C.

Sub Test()
  Dim R1 As Integer, R2 As Integer, R As Integer, NR As Integer
  NR = ActiveSheet.UsedRange.Rows.Count
  Columns(3).Clear
  For R1 = 1 To NR
    If Not IsEmpty(Cells(R1, 1)) Then
      For R2 = 1 To NR
        If Not IsEmpty(Cells(R2, 2)) Then
          R = R + 1
          Cells(R, 3) = Cells(R1, 1) & " - " & Cells(R2, 2)
        End If
      Next R2
    End If
  Next R1
End Sub
