There are many excellent introductory-level explanations of what JSON is, and how to use it here on CodeProject, and, of course, on the web. You have clearly made no effort to help yourself; come back after you have "tried something," with specific questions.

Google for "JSON helper in C#", it may recommend you to use Json.NET; which is a library to work with JSON data in C# applications.

Try with below code:

Create a custom class for type of data serialization:

C#

class employee
{
	public int id { get; set; }
	public string name { get; set; }
}

Create an employee object and serialize it to store in .json file. Add reference System.Web.Extensions and use namespace System.Web.Script.Serialization :

C#

employee eObj = new employee()
{
	id = 90,
	name = "manas"
};

string json = new JavaScriptSerializer().Serialize(eObj);

//write string to file
System.IO.File.WriteAllText(@"C:\path.json", json);

Json file is plain text. You can make use if static methods in File class read/write data to it. You may choose Stream if files are huge.

Note that with these methods, you will need to ensure that you are using correct JSON format.

Alternatively,

-> you can read the JSON, deserialize it into an object. 
-> Create more objects of same class or change data in existing object.
-> Serialize objects to json
-> Overwrite/append the file as per your need

This is not a solution; it's advice. And, there really is no "question" here: the OP clearly hasn't made any effort.

You just summarized 89.334% of Q & A. :)

I don't want to give out code. These pointers should help OP to write something by themselves.
