Parsing JSON in Ruby
We can use Ruby’s JSON.parse function to convert JSON data into a format that Ruby can understand. When you provide a JSON string as input to this method, it will give you back a Ruby hash or array, depending on how the JSON data is organized.
Below is the Ruby program to parse JSON:
require 'json'
json_string = '{"name": "Alice", "age": 25, "city": "London"}'
parsed_data = JSON.parse(json_string)
puts parsed_data
Output:
We can also parse JSON from a file using the following code:
require 'json'
file = File.read('path/to/your/json_file.json')
parsed_data = JSON.parse(file)
puts parsed_data
