Pandoc http://johnmacfarlane.net/pandoc/index.html can do that and much more.
The only "convert X.txt to Y.txt" task that pandoc can not handle is X=wikipedia
But there is definitely sufficient motivation just google "convert wikipedia to" for some examples. I think that the arcane syntax is a big lockin factor with large wikipedia based sites...
There is a ticket for it: https://github.com/jgm/pandoc/issues/388
