Not sure if you have deserialized the json already. But you can do it like this. Create 2 classes and deserialize with Newtonsoft.Json. Then use Linq with SelectMany to get a list of single object.

//deseralize the json
var list1 = JsonConvert.DeserializeObject<List<List<Class2>>>(json);

//select all the nested items
var list2 = list1.SelectMany(x => x).ToList();

The classes

public class Class1
{
    public List<Class1> list { get; set; }
}


public class Class2
{
    public int id { get; set; }
    public string name { get; set; }
    public string email { get; set; }
}
