Frequently Asked Questions
What is JSON?▼
JSON (JavaScript Object Notation) is a lightweight data format used to exchange data between a server and a client. It is human-readable and easy to parse.
How do I validate JSON?▼
Paste your JSON into the editor - the tool will instantly validate it and highlight any syntax errors with line numbers and descriptions.
What is the difference between formatting and minifying?▼
Formatting (beautifying) adds indentation and newlines to make JSON readable. Minifying removes all whitespace to make the JSON as compact as possible for transmission.
