Subject: to_json / to_xml: where to find?

I'm trying to use to_xls, but are running into documentation problems:
Instead of completely describing the options, the author writes:

  "The builder options are the same as to_json / to_xml, except for the
:include."

The same did the guy who wrote to_csv. Really great.

I can't find neither to_json nor to_xml. Where to find these gems?
