JSON Formatter & Validator
Beautify, minify, and validate JSON data in real-time.
What is a JSON Formatter?
A JSON Formatter is a tool that takes a string of JSON (JavaScript Object Notation) and adds line breaks and indentation to make it readable for humans. It also checks if the JSON is valid according to RFC 8259 standards.
Why use our JSON tool?
- Privacy First: All processing happens in your browser. No data is sent to any server.
- Validation: Instant error messages help you identify where your syntax is broken.
- Minification: Strip away whitespace to reduce payload size for production APIs.
