If you have Windows open up the calculator and go to view scientific. Then you can convert small pieces of your code one group at a time.

To do it by hand you divide by 16 until you get zero and then you combine the remainders.

Dim input As String = "BF C2 FF 12 65 E4 EE 17 BF C2 64 [...]"
For Each s As String In input.Split(" "c)
    Dim value As Integer = Convert.ToInt32(s, 16)
    Console.Write(value & " ")    ' Or whatever else you want to do with the converted data
Next

You should tell us your input and wanted output format. I assumed you have the data in a String variable named "input" and want it as byte array.

Dim input As String = IO.File.ReadAllText("C:\data.txt")
Dim output As Byte() = input.Split(" ").Select(Function(b) Convert.ToByte(b, 16)).ToArray

Edit:

For Each part As String In IO.File.ReadAllText("C:\data.txt").Split(" ")
    If part.Trim.Length > 0 Then
        Dim number As Integer = Convert.ToInt32(part, 16)
        Console.Write(number & ",")
    End If
Next
