CSV stands for comma-separated values.
For each item of data you're storing, you can have multiple attributes separated with commas.
In the following code we create a CSV file.
Each line represents a different person, and commas separate the attributes relating to each person.
The commas allow you to access each attribute separately.
Ruby's standard library includes a library called csv to use text files containing CSV data.
require 'csv' File.open("test.txt", "w") do |f| f.puts "Java,Manager,Logic,45\n" f.puts "Json,Data,Female,23\n" f.puts "Database,DBA,Female,38\n" end # w ww . j a v a2s. c o m puts CSV.read('text.txt').inspect CSV.open('text.txt', 'r').each do |person| puts person.inspect end people = CSV.parse(File.read('text.txt')) puts people puts people puts people
CSV.parse converts the data into an array of arrays.
The elements in the main array represent each line in the file.
Each element in those elements represents a different attribute of that line.
