What Is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for both humans and machines to read, write, parse, and generate. It's based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition. JSON has language-independent text format, yet familiar to programmers of C-family languages. JSON facilitates seamless data interchange across various systems, making it an ideal choice for diverse applications.
