Cloaca

Cloaca provides a library of transformations for CSV files and other row structured data.

It does this by providing command-line operations for manipulating a data stream. Operations can be concatenated to perform more complex file transformations.

Installation

Add this line to your application's Gemfile:

gem 'cloaca'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cloaca
