You could create a method:

public string AddObjectsToJson(string json, List objects)
{
    List list = JsonConvert.DeserializeObject>(json);
    list.AddRange(objects);
    return JsonConvert.SerializeObject(list);
}

Then use it like this:

string baseJson = "[{\"id\":\"123\",\"name\":\"carl\"}]";
List personsToAdd = new List() { new Person(1234,"carl2") };

string updatedJson = AddObjectsToJson(baseJson, personsToAdd);
