Excel - A macro to combine selected rows


I have source data in Excel looking like this:

CustomerID SalesMonth SalesAmount
12345 Jan 150 
12345 Mar 100 
12345 Apr 200 
56789 Jan 800 
56789 May 10 
78945 Nov 20 
44444 Jan 1000 

The combination of CustomerID and SalesMonth is unique.

And I would like to combine the source data in a different Excel tab in a form like this:

CustomerID 1stMonth 1stAmount 2ndMonth 2ndAmount 3rdMonth 3rdAmount
12345 Jan 150 Mar 100 Apr 200 
56789 Jan 800 May 10 
78945 Nov 20 
44444 Jan 1000 

In total there can be up to 10 different months for a customer (some have only 1 or 2). Important is that there are no 'gaps' in any of the output rows, eg if a customer has sales only in Nov, then the '1stMonth' cell should read 'Nov' for that customer.


Try this macro and see sheet 2(copy data in sheet 1 to sheet 3 as safety precaution)

Sub test()
Dim customer As Range, ddata() As Range, custunq As Range, cunq As Range, filt As Range
Dim dest As Range, j As Long, k As Long
With Worksheets("sheet1")
Set customer = Range(.Range("A1"), .Range("A1").End(xlDown))
Set custunq = .Range("A1").End(xlDown).Offset(5, 0)
customer.AdvancedFilter xlFilterCopy, , custunq, True
Set custunq = Range(custunq.Offset(1, 0), custunq.End(xlDown))
For Each custunq In custunq
.Range("A1").CurrentRegion.AutoFilter field:=1, Criteria1:=custunq.Value
Set filt = .Range("A1").CurrentRegion.Offset(1, 0).Resize(Rows.Count - 1, Columns.Count). _
  j = WorksheetFunction.CountA(filt.Columns(1))
  'MsgBox j
  ReDim ddata(1 To j)
  With Worksheets("sheet2")
  Set dest = .Cells(Rows.Count, "A").End(xlUp).Offset(1, 0)
dest = filt(1, 1)
End With
  For k = 1 To j
   Set ddata(k) = .Range(filt(k, 2), filt(k, 3))
   With Worksheets("sheet2")
.Cells(dest.Row, Columns.Count).End(xlToLeft).Offset(0, 1).PasteSpecial
End With
Next k
Next custunq
Range(.Range("a1").End(xlDown).Offset(1, 0), .Cells(Rows.Count, "A").End(xlUp)).EntireRow.Delete

End With
End Sub

Sub undo()
End Sub
