Free Online JSON Beautifier
Our JSON beautifier transforms compressed, minified JSON into beautifully formatted, readable code. Whether you're debugging an API response, reviewing configuration files, or learning JSON structure, proper formatting makes everything easier.
Why Beautify JSON?
Minified JSON is designed for machines - it's compact but nearly impossible for humans to read. Beautifying adds proper indentation and line breaks, making nested objects and arrays clearly visible. This is essential for debugging, code review, and understanding data structures.

JSON Best Practices
Use 2-space indentation for most projects - it's the industry standard. Always validate JSON before sending to production. Use meaningful key names and consistent data types. Consider using JSON Schema for complex data validation.
