JSON Formatter and Validator
Paste JSON to validate its syntax, format it for reading, or minify it for compact API payloads. Processing happens in your browser.
Your formatted JSON will appear here.
Why format JSON?
Formatted JSON makes nested objects, arrays and field names easier to inspect during debugging. Minified JSON removes extra whitespace without changing the data. If validation fails, check for single quotes, trailing commas and Python literals such as True or None.
