title: Save a file in json format using Notepad++
body: <p>I have a json format (let's say text) in Notepad++.</p>
  
  <p>I want to save it as a <code>json</code> file using filename.json format.</p>
  
  <p>How can I make it in <code>Notepad++</code> (because I can't find the extension when I go to save as option)</p>
