Generating JSON in Ruby
In Ruby, the JSON.generate method allows you to convert a Ruby hash or array into JSON format. Simply provide a Ruby hash or array as input to this method, and it will produce a JSON string as output. This makes it convenient for creating JSON data from within your Ruby code.
Example:
require 'json'
ruby_hash = {"name" => "Bob", "age" => 30, "city" => "New York"}
json_string = JSON.generate(ruby_hash)
puts json_string
Output:
Below is the Ruby program to parse JSON and write it to a file using the following code:
require 'json'
ruby_hash = {"name" => "Bob", "age" => 30, "city" => "New York"}
File.open('path/to/your/output_file.json', 'w') do |file|
file.write(JSON.pretty_generate(ruby_hash))
end
