Input JSON

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write, and it is easy for machines to parse and generate.

It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages.

Key Features

Human Readable

JSON structure mimics the objects and arrays found in most programming languages, making it intuitive to understand.

Language Independent

While derived from JavaScript, JSON parsers exist for almost every programming language (Python, Java, Go, etc.).

Data Interchange

It is the standard format for REST APIs and web services, effectively replacing XML in modern web development.
