What Is the JSX Formatter?

JSX is JavaScript with XML-like syntax for React components. The JSX Formatter adds indentation and line breaks to JSX/React code. The React JSX docs define the syntax. Standard JavaScript formatters may not handle JSX correctly.

This tool runs entirely in your browser. Nothing is sent to a server. Paste JSX or upload a .jsx or .js file; get formatted output. For plain JavaScript, use JavaScript Formatter. For validation, use JavaScript Validator. For TypeScript conversion, use JavaScript to TypeScript.

How to Use This Tool

1

Paste or Upload

Paste JSX or React code into the left panel or upload a .jsx or .js file. Use Sample to load example code. Use Clear to reset.

2

Check the Output

The right panel shows formatted JSX with proper indentation. Invalid JSX will show an error.

3

Copy or Download

When the JSX Formatter Helps

When working with React, Next.js, or other JSX-based frameworks, this formatter handles the mix of JavaScript and XML. Great for components, hooks, and JSX templates. Build tools like webpack and Vite often use Babel to transform JSX. For plain JS, use JavaScript Formatter.

Frequently Asked Questions

Is my data private?

Yes. Formatting runs entirely in your browser. No data is sent to any server.

JSX Formatter vs JS Formatter?

JSX Formatter understands JSX syntax (tags, props). JS Formatter is for plain JavaScript. Use JSX Formatter for React code.

Does it support TypeScript/TSX?

It may handle TSX in some cases. For TypeScript-focused formatting, check the output.

What about Vue templates?

Vue uses a different template syntax. This tool is for JSX/React.

Can it minify JSX?

For minification, use JavaScript Minifier or a build tool like webpack or rollup. Prettier is another popular formatter for JSX.
