Why convert HTML to JSX?
React uses JSX, a syntax extension that looks like HTML but operates as JavaScript. Browsers cannot read JSX directly; it must be compiled into standard JavaScript. Because JSX is JavaScript under the hood, it enforces different attribute naming conventions than standard HTML.
For instance, the HTML attribute class conflicts with the JavaScript reserve keyword class (used to define ES6 classes). To prevent conflicts, JSX uses camelCase naming: class becomes className, and for becomes htmlFor. Converting these properties manually is time-consuming. Using an automated converter ensures your code is React-ready.
Key Transformations
- Class name mapping: Converts
class="btn"toclassName="btn". - For attribute mapping: Converts
<label for="id">to<label htmlFor="id">. - Self-Closing tags: Tags like
<img>,<input>,<br>, and<hr>must be explicitly closed in JSX (e.g.<input />). - Inline Style Objects: Standard HTML style strings (e.g.
style="color: red; margin: 10px;") are converted into React style objects (e.g.style={{color: "red", margin: "10px"}}).
How to Use this Tool
- Paste your HTML code block in the left panel.
- The JSX translation will instantly appear in the right panel.
- Click "Copy" to export the code, then paste it directly into your React component structure.
