      "id": "0468874507",
      "attributes": {
        "msn": "0468874507",

    },
    
    {
      "type": "products",
      "id": "4000",

        "included-credit": null,

    }
  ]
}

First create an object of SmartJsonParser as below, the module will expect path of the json file as a parameter

parser_object = SmartJsonParser.new('collection.json')

1. use get_default method to get the value for phone, email, fullname and product name

parser_object.get_default

2. use get method to get the value of any attributes, given that you send attributes as a param in proper format

parser_object.get(attribute)

# where attributes can array or comma separated value but in the format of `parent.child.sub-child...`
# e.g. ["data.id", "data.attributes.title", "data.links"]
# another example ["included.products.attributes.name" "data.id", "data.links"] 

3. In case if you want to get concatenated values e.g title+first-name+last-name etc

parser_object.get(attribute)

# where attribute should be array or comma separated value in format of
e.g. "data.attributes.title+first-name+last-name,inlcuded.products.id"
etc

Run it from irb

require 'smart_json_parser'
x = SmartJsonParser.new('collection.json')
x.get_default
x.get("included.products.attributes.name")
