Requirement:
The user needs to extract all the letters within the string, separated by comma.
Now the code extracts first letters only.
Please your help with modifying an user defined function:
Function ExtractLetter(str As String)
    Dim TDCode As String
    Dim result As String
    
    On Error GoTo ErrHandler:
    With CreateObject("vbscript.regexp")
        .Pattern = "[A-Z]+"
        ExtractLetter = .Execute(str)(2)
    End With
    Exit Function
ErrHandler:
End Function
Input: HKJ234CBV546LL
Output (is): HKJ
Output (ought): HKJ,CBV,LL
Solution:
Function RemoveNumbers(Txt As String) As String
  With CreateObject("VBScript.RegExp")
    .Global = True
    .Pattern = "[0-9]"
    RemoveNumbers = .Replace(Txt, " ")
  End With
End Function
Should you need to insert commas between the letters ... you could add following instruction :
RemoveNumbers = Replace(Application.WorksheetFunction.Trim(RemoveNumbers), " ", ",")
