What Is JSON?
 
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is based on a subset of JavaScript and is language-independent, making it a universal format for APIs, configuration files, and data storage.

Frequently Asked Questions
 
Is my data safe?
 
Yes. All formatting and validation happens entirely in your browser. Your JSON data is never sent to any server.
 
What is the difference between JSON and XML?
 
JSON is generally more compact and easier to read than XML. It has become the preferred format for web APIs, while XML is still used in some enterprise systems and document formats like SVG and RSS.
