Aggregate numbers in a cell, the numbers to be separated by commas

Dear Experts:

I got lots of rows populated with numbers. I inserted a column at the very end where all these values are to be aggregated separated by columns. This should be done automatically.

Any idea how this could be done automatically using a formula or VBA code?

Column A     Column B      Column C     Column D      Column E       Aggregate
17                      193                  22                                                             17, 193, 22
83                      244                178               19                     23                 83, 244, 178, 19, 23
55                      343                 44                 23                                          55, 343, 44, 23


As a matter of fact I got 54 Columns.

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

I have attached a sample file for your convenience.

Regards, Andreas

You may try the following User Defined Function. Refer to the attached, I have placed the function in column I.
Function JoinNumbers(ByVal Rng As Range) As String
Dim str As String
Dim cell As Range
For Each cell In Rng
    If cell <> "" Then
        If str = "" Then
            str = cell.Value
        Else
            str = str & ", " & cell.Value
        End If
    End If
Next cell
JoinNumbers = str
End Function

A macro you can use.

Sub Aggregate()
Dim lngLastRow As Long
Dim lngRow As Long
Dim cel As Range

lngLastRow = Range("A1048576").End(xlUp).Row

For lngRow = 1 To lngLastRow
    For Each cel In Range(Cells(lngRow, "A"), Cells(lngRow, "E"))
        If cel <> Empty Then
            Cells(lngRow, "F") = Cells(lngRow, "F") & cel.Value & ", "
        End If
    Next
    On Error Resume Next
    Cells(lngRow, "F") = Left(Cells(lngRow, "F"), Len(Cells(lngRow, "F")) - 2)
Next
End Sub
