Dear Experts:

A copying macro should perform the following tasks:

Run from C2 till the last filled cell in Column C
Take the number of the individual cells in Column C as the number of copies by which the data record is to be copied down (-1)
For example the 'Scissor data' should be listed three times, the Spoon record is to be listed 4 times and the fork record is to be listed twice after running the macro:

Before running macro:

Column A        Column B              Column C
Item_No          Description              Number
17-54               Scissor                            3
17-55               Spoon                            4
17-56               Fork                               2


After running macro:

Item_No      Description      Number
17-54           Scissor                3
17-54           Scissor                3
17-54           Scissor                3
17-55           Spoon                 4
17-55           Spoon                 4
17-55           Spoon                 4
17-55           Spoon                 4
17-56           Fork                     2
17-56           Fork                     2


Help is much appreciated. Thank you very much in advance.

I have attached a sample file for your convenience.

Regards, Andreas

Please find attached.

So you can extend columns A-C, I have put the results into column E-G.

Try this:
Sub Replicator()
    Dim vData
    Dim LR                    As Long
    Dim x                     As Long
    Dim y                     As Long
    Dim j                     As Long
    Dim counter               As Long
    Dim vOut()

    LR = Cells(Rows.Count, "C").End(xlUp).row

    vData = Range("A2:C" & LR).Value
    ReDim vOut(1 To Application.Sum(Range("C2:C" & LR)), 1 To UBound(vData, 2))
    counter = 1
    For x = LBound(vData, 1) To UBound(vData, 1)
        For j = 1 To vData(x, 3)
            For y = LBound(vData, 2) To UBound(vData, 2)
                vOut(counter, y) = vData(x, y)
            Next y
            counter = counter + 1
        Next j
    Next x
    Range("A2").Resize(UBound(vOut, 1), UBound(vOut, 2)).Value = vOut
End Sub

Open in new window

All different code doing the same thing I see :) All finished around the same time too:

Sub test()

UsedRange = ActiveSheet.UsedRange.Rows.Count

For i = UsedRange To 2 Step -1
    j = ActiveSheet.Cells(i, 3)
    For k = j - 1 To 1 Step -1
        Set Rng = ActiveSheet.Range("C" & i).EntireRow
        Rng.Copy
        Rng.Offset(1).Insert Shift:=xlDown
    Next
Next


End Sub

Open in new window


I just went for simplicity and readability (somewhat).
