Format and validate JSON using Jsonlint

People who are basically engaged in web development should not be unfamiliar with Douglas Crockford. This dingding famous person once was Yahoo Advanced JS architect, now is PayPal's senior JS architect. It creates the well-known JSON data type, which allows the web world to propagate data in a more streamlined and readable type than XML, as follows (the middle tall and temperamental):

He created the Jsonlint, and today we have a brief introduction.

Because many colleagues, like running a Java unit test or something, sometimes print out a JSON string, the JSON string is lined up and hard to read, especially if you want to know the logical relationship of this payload and the front-end developers who want to deal with it further.

Like the following one jsonpayload:

So how can you quickly make it readable and verify that the JSON is legitimate? That's when we need the jsonlint created by the father of JSON:

Go to the following website: http://jsonlint.com/

We just need it. Jsonpayload pasted into the text box before the format for the checksum:
