you should make a quiz here in the community for that....I suppose, they will love it and produce a lot of code

but anyway, you can start with a regex matcher to separate the Strings and numbers...
somthing like "[0-9]+|[A-Z]+" a good way to test your regex is this great tool: http://basic4ppc.com:51042/regex/index.html

brings for the first lines of your column with the above matchstring:
Match (length=1): H
Match (length=1): 1
Match (length=1): H
Match (length=4): 3000
Match (length=1): X
Match (length=4): 8001
Match (length=1): X
Match (length=4): 9000
Match (length=1): S
Match (length=1): 1
Match (length=1): S
Match (length=4): 2000
Match (length=1): X
Match (length=1): 1
Match (length=1): X
Match (length=4): 8000
