This tutorial covers a simple way to beautify JSON Code in Browser.

Most web browsers show the JSON code in plain text including popular ones like Google Chrome and Mozilla Firefox. JSON code from a website or web application in your web browser is not so easy to understand quickly due to the lack of proper formatting.

Without the formatting, it’s hard to know where a line ends and you have to deep analyze the code to get the idea. This will surely take more time than it supposed to. Larger the code, the more time it takes. In such situation, I prefer to copy-paste the code to a code editor for formatting.

But, there is an ideal solution to this problem. With JSONView, you can easily view JSON code/document with proper formatting right in your web browser.
