Anyone know of a similar tool based on Ruby?

These are command line utilities, why worry about the language? Just pipe data into and out of csvkit's tools and level up!

https://github.com/blambeau/alf is something close, although it does a lot more: "Alf is a commandline tool and Ruby library to manipulate data with all the power of a truly relational algebra approach."

Does not Ruby support pipelines?
