Overview
Re-indents and cleans up JavaScript so it's consistent and easy to read — useful for minified code or code pasted from inconsistent sources.
How to use it
- 1Paste JavaScript code.
- 2The formatted output updates automatically.
How it works
Uses js-beautify, a widely-used JavaScript beautifier, to tokenize and re-indent your code correctly — including strings, template literals and comments — rather than a naive line-based approach that risks breaking code.
Tips
- This re-indents and spaces code consistently; it doesn't rewrite logic or enforce a style guide the way a linter would.
