What is JSON?

As per W3schools, JSON refers to the JavaScript Object Notation. It is a lightweight format for storing and transporting data. JSON is often used when data is sent from a server to a webpage.

JSON Syntax Rules:

  • Data is in name/value pairs.
  • Data is separated by commas.
  • Curly braces hold objects.
  • Square brackets hold arrays.

Our JSON beautifier works well to beautify the given JSON string into a simple format that is easy to understand by humans.


For example:

The JSON String: {"employees":[{"firstName":"John","lastName":"Doe"},{"firstName":"Anna","lastName":"Smith"},{"firstName":"Peter","lastName":"Jones"}]}

We have entered the above JSON into our tool and it beautifies it into the below way:


"employees": [


"firstName": "John",

"lastName": "Doe"



"firstName": "Anna",

"lastName": "Smith"



"firstName": "Peter",
