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? ---

At least to\_json is part of the json library in stdlib, docs at: [http://ruby-doc.org/ruby-1.9/classes/JSON/Ext/Generator/GeneratorMethods/Hash.html](http://ruby-doc.org/ruby-1.9/classes/JSON/Ext/Generator/GeneratorMethods/Hash.html)
