This below code is Convert to Letter function
Function ConvertToLetter(iCol As Integer) As String
Dim iAlpha As Integer
Dim iRemainder As Integer
iAlpha = Int(iCol / 27)
iRemainder = iCol - (iAlpha * 26)
If iAlpha > 0 Then
ConvertToLetter = Chr(iAlpha + 64)
End If
If iRemainder > 0 Then
ConvertToLetter = ConvertToLetter & Chr(iRemainder + 64)
End If
Debug.Print ConvertToLetter & 1
End Function

When i tired to comment ' Call import_wizard(xFileName, xAddress) the code can select multi file and can show on UI, but tired to delete comment Call import_wizard(xFileName, xAddress) can select multi file but it is show only last file from select and not open them file. I not sure it not do ActiveSheet.QueryTables.Add("TEXT;" & xFileName, Range(xAddress)) or not. Could someone please to suggest? Thanks

You need the "(i)" to select each individual file in this code row:
Call import_wizard(xFileName(i), ...
You don't need your "ConvertToLetter" function to convert a column number to the address.
I suggest to calculate the next import column like this:
...
Dim NextColumn As Long
For i = LBound(xFileName) To UBound(xFileName)
NextColumn = (i - 1) * 23 + 1
Call import_wizard(xFileName(i), NextColumn)
Next i
...
Your import routine then has to start like this:
Function import_wizard(ByVal xFileName as String, NextColumn as Long) As String
With ActiveSheet.QueryTables.Add("TEXT;" & xFileName, ActiveSheet.Cells(1, NextColumn))
...
