JSON (JavaScript Object Notation) is a way of storing and exchanging data. The syntax is text and which is easily understandable and makes it quite uncomplicated like the rest of the data exchanging formats. As JSON is text, any JavaScript object can easily be converted into JSON and sent to the server. It uses serializable value which can be key/value pairs and array data types etc.

This Formatter helps you to correct your mistakes and view your collection of information in a tree structure. The data needs to be in text format when being exchanged with the browser and because it is text, any JavaScript sent to a server can be converted to it and any JSON received can be reconstructed to JavaScript because it is based on JavaScript syntax.

The data today mostly is sent via JSON which is better than XML data interchange format. The structure of XML creates large files because of unnecessary closing tags which are a requirement, but in JSON the structure is simple but lengthy. This is why JSON Format Validator can fix any errors made by you by letting you know which line of your code needs attention and also it can be used to re-write your data else you can start a whole new file in our JSON format checker.


As you know by now, it is a data interchanging format which can be called an alternative to XML but XML is a markup language whereas JSON is Object Notation. When it comes to exchanging of data both the languages work the same way, but JSON is lightweight, which is one of many reasons why it is preferred.

The format of JSON is quite simple to understand as it consists of a few elements which are Objects, values of these Objects, arrays, and Booleans. You will be able to find an example in our tool which will make it easier to understand if you are a newbie and wish to practice this format.

Objects are surrounded by curly braces and are written in key/value pairs where the value can be a string, an array, an array inside an array, Booleans, or numbers. Colon separates the key and value, and a comma separates the pair of key/value. This will help you better understand the example present in the JSON Formatter; the value in the object can be accessed by using dot notation and brackets.
