JSON Formatter

JSON Formatter is a free, instant, browser-based tool that format and beautify json with syntax highlighting and indentation control. Formatting code is one of the most fundamental steps in any developer's workflow. Poorly formatted code is harder to read, harder to debug, and harder to maintain. Whether you're dealing with minified production output, code received from a third-party API, or simply a messy draft, a good formatter transforms it into clean, consistently indented, human-readable text in an instant.

This tool runs entirely in your browser using JavaScript. Nothing you paste is ever sent to a server — your data stays completely private. There are no rate limits, no account required, and no cost. You can format as much code as you like, as often as you like.

Developers use formatters during debugging sessions to make dense output readable, in code reviews to normalize style, when reading minified library source code, and when documenting or sharing code snippets with teammates. Formatted code is also easier for static analysis tools and linters to process.

Browser-based formatters are especially useful when working on machines where you don't have your usual editor or extensions installed — such as on a colleague's computer, a shared workstation, or a cloud-based IDE. Bookmark this tool and you'll always have a reliable formatter a click away, no matter where you're coding.
