<p>{{domxref("Body")}} mixin의 <strong><code>json()</code></strong> 매서드는 {{domxref("Response")}} 스트림을 가져와 스트림이 완료될때까지 읽는다. 이 메서드는 body 텍스트를 {{jsxref("JSON")}}으로 바꾸는 결과로 해결되는 promise를 반환한다.</p>

<p>A promise that resolves with the result of parsing the body text as JSON. This could be anything that can be represented by JSON — an object, an array, a string, a number...</p>

<h2 id="Example">Example</h2>

<p>In our <a href="https://github.com/mdn/fetch-examples/tree/master/fetch-json">fetch json example</a> (run <a href="http://mdn.github.io/fetch-examples/fetch-json/">fetch json live</a>), we create a new request using the {{domxref("Request.Request")}} constructor, then use it to fetch a <code>.json</code> file. When the fetch is successful, we read and parse the data using <code>json()</code>, then read values out of the resulting objects as you'd expect and insert them into list items to display our product data.</p>

<pre class="brush: js">var myList = document.querySelector('ul');

var myRequest = new Request('products.json');

fetch(myRequest)
  .then(function(response) { return response.json(); })
  .then(function(data) {
    for (var i = 0; i &lt; data.products.length; i++) {
      var listItem = document.createElement('li');
      listItem.innerHTML = '&lt;strong&gt;' + data.products[i].Name + '&lt;/strong&gt; can be found in ' +
                           data.products[i].Location +
                           '. Cost: &lt;strong&gt;£' + data.products[i].Price + '&lt;/strong&gt;';
      myList.appendChild(listItem);
    }
  });</pre>
