This library provides a complete interface to CSV files and data. It offers tools to enable you to read and write to and from Strings or IO objects, as needed.

Add this line to your application's Gemfile:

gem 'csv'

And then execute:

$ bundle

Or install it yourself as:

$ gem install csv

require "csv"

CSV.foreach("path/to/file.csv") do |row|
  # use row here...
end

• API: all classes, methods, and constants.
• Recipes: specific code for specific tasks.

After checking out the repo, run ruby run-test.rb to check if your changes can pass the test.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
