What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write, and easy for machines to parse and generate. It's widely used in web APIs, configuration files, and data storage.

Privacy

Your JSON data never leaves your browser. All formatting and validation happens locally using JavaScript, ensuring complete privacy and security for your data.
