Frequently asked questions

How do I format a React component online?

Paste the JSX or TSX into the tool. It uses js-beautify in e4x mode so JSX tags are indented properly, and you can set indentation and newline preservation.

Does it work with TSX?

Yes, the tool beautifies and minifies both JSX and TSX code.

Can I minify JSX?

Yes, there is a minify mode. It reduces whitespace in the code as text and does not compile JSX to JavaScript.

Does it fix errors in my JSX?

No. It only reformats the code, so invalid JSX stays invalid.

Is my data uploaded to a server?

No. This tool runs entirely in your browser — your input is processed locally on your device and is never uploaded or stored on a server.
