Require 'csv' csv.foreach ('file.csv') do |row| # do something with the row puts row.inspect end the ‘foreach’ method will go through each row in the csv. End # or row = csv.shift # writing: New (string_or_io, ** options) # reading: Web the first line in the code below require csv makes ruby’s csv library available to your program so that you can then use the class csv.
