What is JSX Formatter?

JSX Formatter lays out JSX and React component markup so nested elements, expression containers, and surrounding JavaScript are easy to follow. Each element is placed on its own line with consistent indentation, while inline comparisons, for-loops, and destructured props are preserved as written. It is a lightweight, browser-side formatter focused on indentation and line breaks, not a full JavaScript compiler, so it never rewrites your logic.

How to Use JSX Formatter

1

Paste JSX or a React component.

2

Choose indentation style.

3

Click Format.

4

Review the formatted JSX.

5

Copy or download the .jsx file.

Common Use Cases

  • Tidying a minified component copied from a build output or sandbox.
  • Indenting JSX pasted from a chat message or forum answer.
  • Making nested element trees readable before review.
  • Preparing component snippets for documentation or slides.

Example Input and Output

A single-line element tree is expanded with indented children.

Minified JSX
<ul><li>One</li><li>Two</li></ul>
Formatted JSX
<ul>
  <li>
    One
  </li>
  <li>
    Two
  </li>
</ul>

Privacy

JSX is formatted locally in the browser and is not uploaded.

Frequently Asked Questions

Does this validate or compile JSX?

No. It formats text for readability only. Use Babel, ESLint, or your bundler to validate JSX.

Does it understand the difference between a tag and a less-than sign?

Yes. A "<" that follows an identifier or number is treated as a comparison, while one in element position is treated as a JSX tag.

Are destructured props and expression containers preserved?

Yes. Destructured props stay inline and {expression} containers are kept together so the markup stays valid.

Is my code uploaded anywhere?

No. Formatting runs entirely in your browser.
