How Can I Format JSON Output in C# for Better Readability?

Format JSON using C# in .NET

When serializing JSON from a configuration file, you may prefer to use a more readable format with appropriate indentation and newlines. This article solves this problem by recommending JSON.Net as an alternative to JavaScriptSerializer.

Formatting using JSON.Net

JSON.Net is a popular .NET JSON library that supports various formatting options. Here is an example of how to format JSON using JSON.Net:

<code class="language-csharp">using Newtonsoft.Json;

Product product = new Product
{
    Name = "Apple",
    Expiry = new DateTime(2008, 12, 28),
    Price = 3.99M,
    Sizes = new[] { "Small", "Medium", "Large" }
};

string json = JsonConvert.SerializeObject(product, Newtonsoft.Json.Formatting.Indented);
Console.WriteLine(json);</code>

Output:

The above code produces the following formatted JSON output:

<code class="language-json">{
  "Sizes": [
    "Small",
    "Medium",
    "Large"
  ],
  "Price": 3.99,
  "Expiry": "/Date(1230447600000-0700)/",
  "Name": "Apple"
}</code>

JSON.Net’s Formatting.Indented option indents the JSON output, making it easier to read and understand.
