How to Convert JSX to JavaScript - Step by Step Guide

Step 1

Input Your JSX Code

Enter your JSX code to see how it's compiled to JavaScript! Whether you're learning React internals, debugging JSX compilation, or understanding React.createElement, this tool helps you understand the transformation:

•
Paste directly: Copy your JSX code and paste it
•
Upload a file: Upload .jsx or .js files
•
Try the sample: Click "Sample" to see an example

Example: JSX Input

Standard JSX code:

<div className="container">
  <h1>Hello World</h1>
  <button onClick={handleClick}>Click</button>
</div>
Step 2

Automatic Conversion to React.createElement

The tool instantly converts your JSX to React.createElement calls using the industry-standard Babel parser. This powerful transformation, used by build tools and React presets, handles all JSX syntax accurately:

•
Transforms elements: Converts JSX tags into React.createElement function calls with proper element types
•
Handles props: Properly processes all attributes, including event handlers, className, and data attributes
•
Nested components: Correctly nests children elements and maintains the component hierarchy
•
Expression support: Preserves JavaScript expressions within curly braces for dynamic content

Example: JavaScript Output

How JSX transforms to React.createElement calls:

React.createElement(
  "div",
  { className: "container" },
  React.createElement("h1", null, "Hello World"),
  React.createElement("button", { onClick: handleClick }, "Click")
)
Step 3

Use the JavaScript Code

Now you have clean, readable JavaScript code that shows exactly how React interprets your JSX. Use it for various purposes:

•
Copy to clipboard: Quick one-click copy to use in your code editor or documentation
•
Download as file: Save the converted JavaScript as a .js file for reference or sharing
•
Learn React internals: Understand how JSX syntax translates to actual JavaScript function calls
•
Debug JSX issues: See exactly what React.createElement receives to troubleshoot rendering problems

Example: Complex Component Conversion

JSX with nested elements and props:

<Card className="product-card">
  <Image src="/product.jpg" alt="Product" />
  <div className="content">
    <h2>{product.name}</h2>
    <Price value={product.price} currency="USD" />
    <Button onClick={() => addToCart(product.id)}>
      Add to Cart
    </Button>
  </div>
</Card>

Converted JavaScript showing the full React.createElement structure:

React.createElement(
  Card,
  { className: "product-card" },
  React.createElement(Image, { src: "/product.jpg", alt: "Product" }),
  React.createElement(
    "div",
    { className: "content" },
    React.createElement("h2", null, product.name),
    React.createElement(Price, { value: product.price, currency: "USD" }),
    React.createElement(
      Button,
      { onClick: () => addToCart(product.id) },
      "Add to Cart"
    )
  )
)

Frequently Asked Questions

What is React.createElement?

React.createElement is the JavaScript function that JSX compiles to. When you write JSX, tools like Babel transform it into React.createElement calls. This converter shows you that transformation.

Why convert JSX to JavaScript?

Converting JSX to JavaScript helps you understand how React works under the hood, debug compilation issues, and learn what JSX syntax actually does. It's educational and useful for troubleshooting.

Can I use the output in production?

Yes, but it's not recommended. Modern React projects use build tools like Babel or TypeScript to handle JSX transformation automatically. This tool is primarily for learning and debugging purposes.

Is this converter free?

Yes, completely free with no limitations. Perfect for students learning React and developers debugging JSX issues.
