JavaScript formatter

Local only

Your JavaScript

Everything stays in your browser

Your text is processed on your device — nothing is uploaded to a server.

Formatting only adds line breaks and indentation between statements and blocks. String and template literals are detected and left untouched.

This is a lightweight indenter, not a full parser. It handles everyday scripts well; for very unusual syntax, check the output before using it.

Good to know

Does it change my code?

No. Only whitespace outside strings is adjusted.

Does it handle template literals?

Yes. Content inside backticks, single and double quotes is preserved as-is.

Is my code uploaded?

No. Formatting runs entirely in your browser.

Does it support TypeScript or JSX?

Basic structures format fine, but JSX and complex generics may not indent perfectly.
