By "JSON format" do you mean "Javascript Object format"?

Yes, JSON stands for Java Script Object Notation.

You Can construct the JSON object for the list by using
System.Web.Script.Serialization.JavaScriptSerializer jSearializer = 
                   new System.Web.Script.Serialization.JavaScriptSerializer();
string jsonData = jSearializer.Serialize(userList);//userList means your list<> object

Now you can write jsonData to the file using
System.IO.File.AppendAllText(@"C:\Output.txt",jsonData);// You can use your own file path here

List<object> mylist;

string json = mySerializerOfChoiceToJSON(mylist); // replace this with the serializer you want
File.WriteAllText("filename.ext", json); // set your file name here
