Make your structure in JavaScript and try JSON.stringify + JSON.parse .

Example:

var School = {
  Section: [
    {
      User: [
        {
          Name: "John Doe"
        },
        {
          Name: "Jane Doe"
        }
      ]
    }
  ]
};

var str = JSON.stringify(School);
// This gives `{"Section":[{"User":[{"Name":"John Doe"},{"Name":"Jane Doe"}]}]}`

var _school = JSON.parse(str);
// This works great!

var name = _school.Section[0].User[1].Name;
// This gives `Jane Doe`.
