5 Free Online Tools To Beautify And Validate JSON Data

The exponential expansion of the world wide web has caused the usage of JavaScript to increase at a very rapid rate. JavaScript has become one of the most crucial languages of information technology in development. The basic motive to develop JavaScript is to extend the platforms of web applications. JavaScript offers the service of JSON i.e. JavaScript Object Notation. Nowadays, JSON has become the standard tool to store structured data. It has become the default computer readable format in most of the cases. 

JSON represents a format with a number of data types including lists, booleans, null, strings and numbers. Because JSON representation is compatible with all kinds of programming languages, JSON becomes a potential solution for transmission of data across language gaps. 

This article discusses the free online JSON validators to beautify and validate JSON data.  

Why JSON ?
