Frequently Asked Questions
JSX is a syntax extension for JavaScript, used with React to describe UI structure. It looks similar to HTML but allows you to embed JavaScript expressions inside curly braces.
When migrating static HTML to a React application, you need JSX to use components, state, and props. This converter automates the repetitive attribute renaming and style adjustments.
It converts CSS strings like
color: red; font-size: 12px into JSX style objects: style={{ color: 'red', fontSize: '12px' }}. You can disable this option if you prefer to keep the original string (not recommended for React).By default, event handlers (like
onclick) are removed because inline event strings cannot be directly used in React. You will need to rewrite them as React event handler functions. Uncheck “Remove event handlers” if you want to keep them for manual editing.Yes, the converter runs entirely in your browser. However, extremely large files (several MB) may slow down your tab. For such cases we recommend splitting the HTML into smaller fragments.
