A tester, résultat en Feuil2 :
Option Explicit
Sub test()
Dim a, i As Long, j As Long, n As Long, col As Byte, w
a = Sheets("Feuil1").Range("A3").CurrentRegion.Value
col = UBound(a, 2): n = 1
With CreateObject("Scripting.Dictionary")
For i = 2 To UBound(a, 1)
If Not .exists(a(i, 1)) Then
n = n + 1: .Item(a(i, 1)) = VBA.Array(n, col)
For j = 1 To col
a(n, j) = a(i, j)
Next
Else
w = .Item(a(i, 1)): w(1) = w(1) + 7
If UBound(a, 2) < w(1) Then
ReDim Preserve a(1 To UBound(a, 1), 1 To w(1))
End If
For j = 1 To 7
a(w(0), w(1) - 7 + j) = a(i, j + 1)
Next
.Item(a(i, 1)) = w
End If
