Online JSON Formatter & Validator
JSON (JavaScript Object Notation) is the language of the web APIs. But raw JSON is often a messy, single-line string that is impossible to read.
Our Free JSON Formatter tool transforms ugly, minified JSON code into a clean, readable tree view. It also validates your syntax, helping you spot missing commas or brackets instantly.
Why use a JSON Formatter?
- Debug Faster: See exactly how your data is structured.
- Fix Errors: Syntax highlighting helps you catch invalid JSON.
- Share Code: Formatted JSON is easier for teams to review.
