Bonjour,
J'y suis arrivé de cette façon.
Probablement pas la plus optimale.
Sub Correspondance()
Application.ScreenUpdating = False
Range("B1:B2").Delete Shift:=xlUp
Range("C1:C4").Delete Shift:=xlUp
Dim derniere_ligne As Long
i = 1
derniere_ligne = Cells(Rows.Count, 1).End(xlUp).Row
For j = 2 To derniere_ligne
If Range("A" & i) <> "" And Range("A" & i + 1) = "" Then Range("A" & i).Copy Range("A" & i + 1)
i = i + 1
Next
Application.ScreenUpdating = True
End Sub
