Convert JSON to DataTable

There is an easier method than the other answers here, which require first deserializing into a c# class, and then turning it into a datatable.

It is possible to go directly to a datatable, with JSON.NET and code like this:

DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));

Deserialize your jsonstring to some class

List<User> UserList = JsonConvert.DeserializeObject<List<User>>(jsonString);

Write following extension method to your project

using System.ComponentModel;public static DataTable ToDataTable<T>(this IList<T> data){    PropertyDescriptorCollection props =    TypeDescriptor.GetProperties(typeof(T));    DataTable table = new DataTable();    for(int i = 0 ; i < props.Count ; i++)    {        PropertyDescriptor prop = props[i];        table.Columns.Add(prop.Name, prop.PropertyType);    }    object[] values = new object[props.Count];    foreach (T item in data)    {        for (int i = 0; i < values.Length; i++)        {            values[i] = props[i].GetValue(item);        }        table.Rows.Add(values);    }    return table;        }

Call extension method like

UserList.ToDataTable<User>();

It can also be achieved using below code.

DataSet data = JsonConvert.DeserializeObject<DataSet>(json);
