How to convert a string to lower or upper case in Ruby

Question

How do I take a string and convert it to lower or upper case in Ruby?

Answer 1

Won't work for every, but this just saved me a bunch of time. I just had the problem with a CSV returning "TRUE or "FALSE" so I just added VALUE.to_s.downcase == "true" which will return the boolean true if the value is "TRUE" and false if the value is "FALSE", but will still work for the boolean true and false.
