    This is a simple piece of code for writing data from a two dimensional string array to a comma delimited file for easy reading into excel.

        Sub TwoDArrayToCSV(ByVal DataArray(,) As String)
            Dim str As String = ""
            Dim ofile As String = ""
            svDialog("csv|*.csv", "save as...", ofile)
            Dim sw As System.IO.StreamWriter = New System.IO.StreamWriter(ofile)
            For i As Int32 = DataArray.GetLowerBound(0) To DataArray.GetUpperBound(0)
                For j As Int32 = DataArray.GetLowerBound(1) To DataArray.GetUpperBound(1)
                    str += DataArray(i, j) + ","
                str = ""
        End Sub
        Sub svDialog(ByVal infilter As String, ByVal dtitle As String, ByRef outfile As String)
            Dim openFileDialog1 As New SaveFileDialog()
            With openFileDialog1
                .Filter = infilter
                .FilterIndex = 1
                .Title = dtitle
                .DefaultExt = Strings.Right(infilter, 3)
                outfile = openFileDialog1.FileName
                .RestoreDirectory = True
          End With
        End Sub
