                    temp.batch = tmobj;
                    temp.term = tmobj1;

    { 'batch': '28', 'term': 'Term I', 'section': 'Section II' }      
]

how to convert Newtonsoft json to angular2 object ?

Answer 1

You have a JSON-encoded string in you JSON so you just need to parse it twice:

let final= JSON.parse(data.d);

You just need to use the final value to get the content of your JSON.

However , it is weird that you are receiving data encoded like this, maybe you could tweak the server to get properly-encoded JSON object and not a string.
