What is JSX Formatter?
Got messy JSX (JavaScript XML) code that's hard to read? This tool fixes that. It takes your JSX code and makes it beautiful – proper indentation, line breaks, everything organized. Whether you're working with React components, debugging JSX, or just trying to understand what your code actually says, this makes it readable.
According to React documentation, JSX is a syntax extension for JavaScript that lets you write HTML-like code in your JavaScript. Our formatter follows JSX best practices, so your formatted code is always clean and standards-compliant.
Best part? Everything happens instantly in your browser. No server uploads, no data storage – just paste, format, and copy. Your code stays private.
What Makes This Tool Different
Pretty Print Instantly
Paste minified JSX and get perfectly formatted output in milliseconds. We use consistent indentation so nested elements are easy to read.
JSX Syntax Validation
While we format, we also validate your JSX. If something's broken, we'll show you exactly where so you can fix it fast.
Attribute Formatting
JSX attributes are properly aligned and formatted. Makes it easy to see component props and their values at a glance.
File Upload Support
Got a big file? Just upload it. Works with .jsx and .js files. No need to copy-paste – just drag and drop or click upload.
Copy & Download
One click to copy, or download it as a file. Perfect for saving formatted versions or sharing with your team.
Syntax Highlighting
Our editor provides beautiful syntax highlighting. JSX tags, attributes, and JavaScript expressions are color-coded for easy reading.
How It Works
Paste or Upload JSX
Paste your JSX code into the left editor, or click "Upload" to load a file. You can also click "Sample" to see example JSX. The tool accepts any valid JSX structure – components, props, nested elements, you name it.
Automatic Formatting
As soon as you paste, the formatter processes your JSX and displays the beautifully formatted version on the right. Nested elements get proper indentation, attributes are aligned, and everything is organized perfectly.
Copy or Download
Click "Copy" to copy the formatted JSX to your clipboard, or "Download" to save it as a file. All processing happens instantly in your browser.
When You'd Actually Use This
React Development
Format JSX components to understand the structure, debug issues, or improve readability. Works great with React components or any JSX-based code.
Code Review
Reviewing JSX code? Format it first to see the structure clearly. Makes it easier to spot errors, understand component hierarchy, or compare different implementations.
Learning JSX
New to JSX? Formatting helps you understand the syntax. See how components nest, how props work, and how JSX structures are organized. Much easier than reading minified code.
Debugging
Trying to find a bug in your JSX? Formatting reveals the structure, making it easier to spot missing closing tags, incorrect nesting, or prop issues. The validation feature catches syntax errors instantly.
Common Questions
Is my JSX code stored?
No. All formatting happens in your browser using JavaScript. Your JSX never leaves your computer.
What JSX formats are supported?
We support all valid JSX according to React standards. Components, props, nested elements, JavaScript expressions – everything standard JSX supports.
Can I format invalid JSX?
We'll try to format it, but if there are syntax errors, the output might not be perfect. Fix syntax errors first for best results.
What indentation does it use?
We use consistent spacing for indentation, making nested structures easy to read. The exact style follows common JSX formatting conventions.
How big can my file be?
Since processing happens in your browser, performance depends on your device. Small files format instantly. Very large files (several MB) might take a few seconds, but they'll still work.
Does it work with TypeScript JSX?
Yes, we support TSX (TypeScript JSX) files as well. The formatting works the same way, preserving TypeScript syntax while formatting JSX structure.
Other JavaScript Tools You Might Need
Formatting is just one JSX task. Here are other tools that work well together:
