How to Format JSX/React Code - Step by Step Guide

Step 1

Input Your JSX/React Code

Let's get your JSX code into the formatter! Whether you're working with React components, building modern web applications, or want to ensure consistent code style, you have several convenient options:

•
Paste directly: Copy your React component or JSX code and paste it into the input editor
•
Upload a file: Click "Upload" to select a .jsx, .js, .tsx, or .txt file from your computer
•
Try the sample: Click "Sample" to load example React component code and see how the formatter works

Example: Unformatted JSX Input

Here's what messy, unformatted JSX looks like:

const UserCard=({user})=>{return (<div className="card"><img src={user.avatar} alt={user.name}/><h2>{user.name}</h2><p>{user.email}</p></div>)}
Step 2

Automatic Formatting & Validation

The magic happens instantly! As soon as you input JSX, the formatter automatically:

•
Validates syntax: Checks for JSX errors and highlights issues with helpful suggestions using Prettier
•
Adds proper indentation: Makes nested components and JSX elements easy to read
•
Syntax highlighting: Color-codes different elements for better readability

Example: Beautifully Formatted Output

The same JSX, now properly formatted and readable:

const UserCard = ({user}) => {
  return (
    <div className="card">
      <img
        src={user.avatar}
        alt={user.name}
      />
      <h2>{user.name}</h2>
      <p>{user.email}</p>
    </div>
  )
}
Step 3

Export Your Formatted JSX

Get your perfectly formatted JSX code ready for use! Multiple export options make it easy to integrate into your React workflow:

•
Copy to clipboard: One-click copying for quick pasting into your code editor or IDE
•
Download as file: Save as a .jsx file for later use or sharing with your team
•
Minify option: Click "Minify" to compress JSX for production builds (removes unnecessary whitespace)
•
Real-time validation: Green checkmark confirms your JSX is valid and ready to use in React

Frequently Asked Questions

What is JSX and why do I need a formatter?

JSX is a syntax extension for JavaScript used in React to write HTML-like code within JavaScript. A formatter ensures consistent code style, proper indentation, and readability across your React components, making code maintenance easier and team collaboration smoother.

Does this formatter work with TypeScript (TSX)?

Yes! The formatter handles both JSX (.jsx) and TSX (.tsx) files. It uses Prettier under the hood, which supports TypeScript syntax, ensuring your React TypeScript components are formatted correctly with proper type annotations.

Can I format React Hooks and modern React code?

Absolutely! The formatter fully supports modern React features including Hooks (useState, useEffect, etc.), functional components, arrow functions, and ES6+ syntax. It properly formats all React patterns and best practices.

Does the formatter validate JSX syntax errors?

Yes! The formatter validates JSX syntax and displays clear error messages if there are issues like unclosed tags, invalid attributes, or JavaScript syntax errors. This helps catch bugs early before running your React app. For JavaScript validation, try our JavaScript Formatter.

Can I minify JSX for production builds?

Yes! Click the "Minify" button to compress your JSX code by removing unnecessary whitespace and formatting. This is useful for reducing file size in production, though modern build tools like Webpack or Vite typically handle this automatically.

Is the JSX formatter completely free?

Yes, completely free with no limitations on file size, usage frequency, or features. No registration required, and you can format unlimited JSX/React files with full syntax highlighting and validation. Perfect for React developers of all levels!
