When reading minified or poorly indented third-party code, paste it into the beautifier to get a consistently formatted, readable version that is easier to understand, debug, and review.
The tool applies language-specific formatting rules to the input, normalising indentation, spacing, and brace/bracket placement according to the selected style configuration.
Code is processed in the browser. Avoid pasting code that contains credentials, secrets, or access tokens.
The beautifier applies standard formatting conventions and may not match every team's specific style guide. For project-wide formatting with custom rules and version control integration, use dedicated tools like Prettier, Black, or ESLint with --fix.
