Frequently Asked Questions

Can it fix syntax errors in my code?

No, the formatter expects structurally valid code. If there are missing brackets or severe syntax errors, the formatting may fail or produce unexpected results.

Does it work with TypeScript or React JSX?

The JavaScript formatter handles standard JS well, but specialized syntax in TS or JSX might not format perfectly depending on the complexity.

Is my code sent to a server?

No, all formatting is executed locally within your browser using client-side libraries, ensuring your code remains private.

Can I minify code instead of formatting it?

Currently, the tool focuses solely on beautifying (un-minifying) and structuring code for human readability.
