HTML to JSX Converter


What is HTML to JSX Conversion?

JSX is the HTML-like syntax extension used in React to describe UI structure. Although it looks almost identical to HTML, JSX has important syntactical differences that make it invalid to paste HTML directly into a React component. The main changes: class must be className (class is a reserved word in JavaScript), for must be htmlFor in form labels, all void elements must be self-closed (e.g. <br /> not <br>), inline styles must be JavaScript objects (style={{color: 'red'}} not style="color:red"), and event handlers use camelCase (onClick not onclick). Converting by hand is tedious and error-prone, especially for large HTML templates. This tool applies all necessary transformations automatically.

How to Use the HTML to JSX Converter

  1. Paste your HTML markup into the input panel, or click 'Example' to load a sample.

  2. The JSX output is generated instantly β€” class attributes become className, style strings become objects, etc.

  3. Enable 'Wrap in component' to get a complete React functional component with import and export.

  4. Customise the component name if needed.

  5. Click 'Copy JSX' to copy the output to your clipboard.

Frequently Asked Questions

What HTML attributes are transformed? The converter transforms: class β†’ className, for β†’ htmlFor, all inline style strings β†’ JavaScript style objects, and self-closes void elements (img, br, hr, input, etc.). HTML comments are preserved as JSX comments {/* ... */}.

Does this work with SVG? Yes. SVG elements use different attribute names than HTML in some cases (e.g. clip-path β†’ clipPath, stroke-width β†’ strokeWidth). The converter handles standard SVG attribute camelCase conversions.

Why does JSX require className instead of class? In JSX, class is a reserved JavaScript keyword used for defining ES6 classes. To avoid a parsing ambiguity, React chose className as the DOM attribute name. Under the hood, React maps className back to the DOM's class attribute when rendering.

Can I paste a full HTML page? The converter works best with HTML fragments (a component's template). For full pages with <!DOCTYPE>, <html>, <head>, and <body>, only the relevant body content is typically needed for a React component.
