JSON FORMATTER
JSON Formatter, Minifier, and Validator
Format, minify, and validate JSON entirely in your browser.
About the JSON Formatter
Format compact JSON with indentation to make keys, arrays, and nested objects easier to review. It is helpful when you need to inspect an API response, a configuration file, or JSON included in application logs.
You can also minify JSON to remove unnecessary whitespace and validate whether text is valid JSON. These checks are useful before sharing a payload, editing a configuration, or narrowing down the cause of a parsing error.
Everything runs in your browser. JSON you paste is not sent to or stored on a server, allowing you to review content without sharing it with this site.
