In Excel, you can copy some data which is 1 row by multiple columns (eg B5:Z5), then paste that data in to a range which is 1 column wide by multiple rows (eg D10:D50) and the data will be repeated in each row. That's what the code below is doing:
Sub MultiCopy()
Dim sourceRange As Range
Dim targetBook As Workbook
Dim targetRange As Range
Dim cell As Range
Dim count As Integer
Dim copyRange As Range
'Adjust this range to reflect the list containing the numbers
Set sourceRange = ActiveSheet.Range("B2:B6")
'We'll copy the data to a new workbook
Set targetBook = Workbooks.Add
Set targetRange = targetBook.Worksheets(1).Range("A1")
'Loop through the cells which contain the number of times to repeat the row
For Each cell In sourceRange
'Get the number of times that the current row will be repeated
count = cell.Value
'The range being copied starts in the cell to the right of the value, and is 5 cells wide
Set copyRange = cell.Offset(0, 1).Resize(1, 5)
'The data will be pasted in to a vertical block of cells
'The copied data gets repeated in each row
Set targetRange = targetRange.Resize(count, 1)
copyRange.Copy targetRange
'Reset the targetrange ready for the next row
Set targetRange = targetRange.Offset(count, 0)
Next
End Sub
I don't have a Mac, but the code below works fine on Excel 2013, and I'm not aware of any reason that it wouldn't work on a Mac.
