How This HTML to JSX Converter Works
Paste HTML into this html to jsx converter and convert html to jsx online instantly, updating in realtime as you type. It's a genuine paste html get jsx workflow for porting a static mockup, a scraped page fragment, or existing markup into a React component, an html to jsx free tool and jsx converter online with nothing to install and no signup.
Attribute Renaming: class to className, for to htmlFor, and More
The two renames every html to react jsx conversion needs are handled first, class becomes className and for becomes htmlFor. Beyond those two, this tool works as a genuine class to classname converter and covers the rest of the JSX attribute map too, tabindex becomes tabIndex, readonly becomes readOnly, colspan and rowspan become colSpan and rowSpan, and more, event handler attributes like onclick and onchange are camelCased to onClick and onChange. data- and aria- attributes are left exactly as written, since JSX already accepts them in their original hyphenated form.
Inline Styles and Void Elements
This tool doubles as a way to convert inline style to jsx, a style="color: red; font-size: 16px" string becomes style={{ color: "red", fontSize: "16px" }}, with each CSS property camelCased the way JSX expects. Void elements, img, br, input, hr, and the rest of the HTML void element list, are automatically self-closed even if the source HTML wrote them without a trailing slash, since JSX requires every element to be explicitly closed.
Component Wrapper and Limitations
For a genuine html to react component converter workflow, an optional toggle wraps the converted markup in a named function component, with html to jsx with fragment support, wrapping the JSX in a <>...</> Fragment when your HTML has multiple top-level siblings that would otherwise need a wrapping element. One honest limitation worth knowing: this is a text-transform tool built on pattern matching, not a full HTML parser, so deeply malformed or unbalanced HTML, unclosed tags crossing unexpected boundaries, may produce JSX that still needs a manual fix before it compiles.
