What this tool is for
JavaScript Beautifier makes compact snippets easier to scan without pulling in a full formatter.
When to use it
Use it for pasted examples, bookmarklets, console snippets, or quick debugging notes.
What the result means
The output adds line breaks and indentation around braces, semicolons, and simple block structure.
Use notes
- This is not a replacement for Prettier or your project formatter.
- Strings and advanced syntax are preserved as plain text.
- Run project code through your real formatter before committing.
Privacy and limits
Everything runs in your browser tab. Avoid pasting production secrets, private tokens, customer data, or proprietary code into any online page unless your team policy allows it.
