Paste JSON to format, validate, beautify, or minify it. Invalid syntax produces a clear error, while valid data becomes clean and readable.
Format API responses and configuration files without rounding large numeric IDs. Only whitespace between tokens changes: decimal and exponent notation, key order, duplicate keys and string escapes stay as written. Duplicate keys can still be interpreted differently by downstream parsers. Input is limited to 1,000,000 characters and 100 nesting levels; output to 5,000,000 characters.
Formatting {"id":9007199254740993,"price":10.50} adds indentation without rounding the ID or rewriting 10.50.
No. Syntax is validated, then the original tokens are preserved. Numbers such as 9007199254740993, decimal and exponent notation, key order and string escapes are not rewritten.
Yes. It reports an error when the pasted content is not valid JSON.
Minified JSON removes optional spaces and line breaks while preserving the same data.
