Frequently Asked Questions

What does the HTML to JSX converter do?▾

It transforms standard HTML into valid React JSX by applying all necessary syntax changes: class becomes className, for becomes htmlFor, inline style strings become JavaScript objects, event handlers become camelCase, void elements get self-closing tags, and HTML comments become JSX comments.

Why do I need to convert HTML to JSX?▾

React uses JSX, which looks like HTML but has strict differences. Using raw HTML in React components will cause errors — for example, 'class' is a reserved word in JavaScript, so React requires 'className' instead. Inline styles must be JavaScript objects, not CSS strings. This converter handles all these transformations automatically.

Does it convert inline styles correctly?▾

Yes. The converter parses CSS style strings and transforms them into JavaScript style objects with camelCase property names. For example, 'font-size: 14px; background-color: red' becomes {{fontSize: '14px', backgroundColor: 'red'}}.

What HTML attributes are converted?▾

The tool converts all standard HTML-to-JSX attribute mappings including class→className, for→htmlFor, tabindex→tabIndex, maxlength→maxLength, readonly→readOnly, and many more. It also converts all event handlers (onclick→onClick, onchange→onChange, etc.) and SVG-specific attributes.

Can I see what changes were made?▾

Yes. The tool displays a changes summary showing exactly how many of each transformation was applied — for example, '3 class → className', '1 style string → object'. This helps you understand what was modified and verify the output.

Is the conversion done locally?▾

Yes, all conversion happens entirely in your browser using JavaScript. No HTML code is sent to any server. Your code stays private and the tool works even offline.
