Bonjour,
Si j'ai bien compris la demande, tu souhaites rajouter "/2" à chaque formule de ta feuille ?
Si c'est ça, à mettre dans le module 4 (vide) et tester (lancer la sub "Test()") :
Sub Test()
Dim Plage As Range
Dim Cel As Range
Set Plage = DefPlage(ActiveSheet)
For Each Cel In Plage.Cells.SpecialCells(xlCellTypeFormulas)
Cel.Formula = Cel.Formula & "/2"
Next Cel
End Sub
Function DefPlage(Fe As Worksheet, Optional L As Long = 1, Optional C As Long = 1) As Range
On Error GoTo Fin
With Fe
Set DefPlage = .Range(.Cells(L, C), _
.Cells(.Cells.Find("*", .[a1], -4123, , _
1, 2).Row, .Cells.Find("*", .[a1], -4123, , _
2, 2).Column))
End With
Exit Function
Fin:
Set DefPlage = Nothing
End Function
