I'm not sure that's possible in a general sense. Is 123 text or a
number? How do I prove it one way or another?

However, if you were happy to end up with "good enough" types (i.e.
might end up using text instead of a more specific type), and know that
data was representative then it shouldn't be too tricky to write some
pattern-matching Perl to do the job.
