Convert .json to .csv in ruby

To actually write to file...

require 'csv'
require 'json'

CSV.open("your_csv.csv", "w") do |csv| #open new file for write
  JSON.parse(File.open("your_json.json").read).each do |hash| #open json to parse
    csv << hash.values #write value to file
  end
end

Try something like this:

require 'csv'
require 'json'

csv_string = CSV.generate do |csv|
  JSON.parse(File.open("foo.json").read).each do |hash|
    csv << hash.values
  end
end

puts csv_string
