A JSX formatter restructures React component code with proper element indentation, attribute-per-line alignment for multi-attribute tags, and consistent spacing around expression blocks. It normalizes component structure so code is readable and ready for code review, whether you paste a single component or a full file with imports and exports.

How to Use the JSX Formatter
JSX code pasted from different editors or generated by tools often has inconsistent indentation, all attributes on one line, or collapsed whitespace. A JSX formatter normalizes component structure so code is immediately readable and consistent with modern React style guides.
Step 1: Paste Your JSX Code
Copy your React component — a single JSX element, a full functional component, or an entire file with imports and exports — and paste it into the input area. The formatter handles JSX syntax including nested elements, expression blocks {}, self-closing tags, and conditional rendering patterns.
Step 2: Configure Formatting Options
Choose 2 or 4 space indentation (2 spaces is the React community standard). Toggle "Multi-attr expand" on to place each attribute on its own line when a tag has more than 2 attributes — this matches the Prettier default and makes attribute-heavy components like form inputs much more readable.
Step 3: Copy or Download
The formatted JSX appears on the right with JavaScript syntax highlighting. Use Copy to paste into your editor or Download to save as a .jsx file. Minify collapses whitespace to the most compact valid form.
JSX Formatting Best Practices
React community standard (from Prettier): 2-space indentation, each JSX attribute on its own line when there are 3 or more, closing angle bracket on its own line, self-closing tags with a space before />. For large components, each major section (imports, component, export) should have a blank line separator. These conventions make components easy to read, diff, and review.
FAQ
Is the JSX formatter free?
Yes, completely free with no signup required. Format unlimited JSX and React component code directly in your browser.
Is my JSX code safe?
Yes. All formatting runs locally in your browser. Your code is never sent to any server.
What does the JSX formatter do?
It indents nested JSX elements, places each attribute on its own line when there are more than 2 attributes, handles self-closing tags, normalizes spacing around expression blocks {}, and groups imports at the top.
Does it support TypeScript JSX (.tsx files)?
Yes. The formatter handles both .jsx and .tsx syntax including TypeScript generic syntax, interface props, and type annotations in component signatures.
Can I minify JSX code?
Yes. The Minify option strips comments, collapses whitespace between tags, and produces compact JSX output. Note that minified JSX is not valid JavaScript — it still needs to be compiled by Babel or a bundler.
Why does the formatter not validate my JSX syntax?
This formatter uses pattern-based formatting for maximum speed without loading a JavaScript parser. For full syntax validation, use your IDE's JSX linting (eslint-plugin-react) or paste your code into a tool like Babel's online REPL.
