About JSONyfier
JSONyfier is a free browser-based suite for formatting, minifying, and validating JSON. Its tools run in the visitor's browser, require no account, and do not upload the JSON entered into them.

What each JSON tool does
- JSON Formatter validates input and pretty-prints parsed values with 2-space indentation and syntax highlighting.
- JSON Minifier validates input, removes insignificant whitespace from the original text, reports UTF-8 byte savings, and supports copy or download.
- JSON Validator checks syntax and reports the first error returned by the browser's JSON parser.
Data handling
JSON tool input stays on the device. The website can load Google Analytics only after the visitor accepts analytics cookies, but the analytics integration is not given the JSON entered into a tool. The privacy policy describes the site's current data processing and visitor rights.
Practical limits
JSONyfier is an interactive browser utility, not a hosted API, JSON Schema validator, JSONC parser, or streaming processor. Standard JSON does not include comments. Available browser memory and performance determine the practical document size.
