Convert numerous files in a folder from csv to xls, while carrying out text to columns

Question

I'm trying to convert multiple csv files to xls whilst carrying out a text to column process. I have two macros below. The Text2cols seems to work fine but the ConvertCSVToXls macro seems to have a few issues. Firstly, its really slow. Secondly, it seems to loop through the same csv again and again. I'm running this macro from my personal workbook. Can anyone see the issue? What i would really like would be to sweep the xls files to a subfolder ("filepath\csv files\converted files" and keep the original csv rather than delete?

Sub Text2cols()
    Dim objRange1 As Range
   

    'Set up the ranges
    Set objRange1 = Range("A:A")


    'Do the first parse
    objRange1.TexttoColumns _
      Destination:=Range("A1"), _
      DataType:=xlDelimited, _
      Tab:=False, _
      Semicolon:=False, _
      Comma:=False, _
      Space:=False, _
      Other:=True, _
      OtherChar:="|"

End Sub
