J'ai trouvé la solution :
With Sheets("Document")
.Sort.SortFields.Clear
.Sort.SortFields.Add Key:=Range("A2:A1000"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
.Sort.SortFields.Add Key:=Range("C2:C1000"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
With .Sort
.SetRange Range("A2:J1000")
.Header = xlGuess
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
End With
