Expanding column cells for each column cell

I gather by universal, you want this to accommodate any number of columns and any number of entries in each. A few variant arrays should provide the dimensions necessary to calculate the cycles of repetition for each value.

Sub main()
    Call for_each_in_others(rDATA:=Worksheets("Sheet3").Range("A3"), bHDR:=True)

            With .Resize(.Rows.Count - (rDATA(1).Row - .Cells(1).Row), .Columns.Count).Offset(2, 0)
                sErrorRng = .Address(0, 0)
                vTMPs = .Value2
                ReDim vCOLs(LBound(vTMPs, 2) To UBound(vTMPs, 2))
                iMAXROWS = 1
                'On Error GoTo bm_Output_Exceeded
                For w = LBound(vTMPs, 2) To UBound(vTMPs, 2)

                End If

                On Error GoTo bm_Safe_Exit

                iINCROWS = 1
                For w = LBound(vVALs, 2) To UBound(vVALs, 2)
                    iINCROWS = iINCROWS * vCOLs(w)
                    For v = LBound(vVALs, 1) To UBound(vVALs, 1)
                        vVALs(v, w) = vTMPs((Int(iINCROWS * ((v - 1) / UBound(vVALs, 1))) Mod vCOLs(w)) + 1, w)

        .Cells(2, UBound(vVALs, 2) + 2).Resize(1, UBound(vVALs, 2) + 2).EntireColumn.Delete
        If bHDR Then
            rDATA.Cells(1, 1).Offset(-1, 0).Resize(1, UBound(vVALs, 2)).Copy _
                Destination:=rDATA.Cells(1, UBound(vVALs, 2) + 2).Offset(-1, 0)
        End If
        rDATA.Cells(1, UBound(vVALs, 2) + 2).Resize(UBound(vVALs, 1), UBound(vVALs, 2)) = vVALs
    End With

    GoTo bm_Safe_Exit
bm_Nothing_To_Do:
    MsgBox "There is not enough data in  " & sErrorRng & " to perform expansion." & Chr(10) & _

           "Single or No Column of Raw Data"
    GoTo bm_Safe_Exit
bm_Output_Exceeded:
    MsgBox "The number of expanded values created from " & sErrorRng & _
           " (" & Format(iMAXROWS, "\> #, ##0") & " rows × " & UBound(vTMPs, 2) & _
           " columns) exceeds the rows available (" & Format(Rows.Count, "#, ##0") & ") on this worksheet.", vbCritical, _

Sub appTGGL(Optional bTGGL As Boolean = True)
    Application.EnableEvents = bTGGL
    Application.ScreenUpdating = bTGGL
End Sub

Put the column header labels in row 2 starting in column A and the data directly below that.

I have added some error control to warn of exceeding the number of rows on a worksheet. This is not normally something that is likely to be a consideration but multiplying the number of values in an undetermined number of columns against each other can quickly produce a large number of results. It is not unforeseeable that you would exceed 1,048,576 rows.
