Format, validate, beautify, and minify JSON online for free. Paste your JSON to instantly check syntax, fix formatting, and make complex JSON easier to read.
A JSON formatter is a tool that converts compact or difficult-to-read JSON into a clean, structured format with indentation and line breaks. This makes JSON easier to read, understand, debug, and work with during web and software development.
Our online JSON formatter also validates your JSON while you work. If the JSON contains a syntax error, the validator identifies the problem so you can correct it before using the data in an application, API, or configuration file.
You can also minify valid JSON to remove unnecessary whitespace and reduce its size. Formatting and validation happen directly in your browser, so your JSON is not uploaded to our server.
