}About JSX Formatter
JSX gets messy fast: nested elements, inconsistent indentation, and mixed quote styles make a component hard to read and harder to review. When you paste in a snippet from somewhere else or refactor in a hurry, the formatting often falls apart. The JSX Formatter cleans up and prettifies your React JSX, giving it consistent indentation and structure so the markup reads clearly and diffs stay tidy.
Paste your JSX, and the tool reformats it into a clean, readable layout you can drop straight back into your component. It runs entirely in the browser, so nothing is uploaded, there is no signup, and the result appears instantly. It is a quick way to tidy a single file, normalize code copied from a tutorial, or make a snippet presentable before sharing it in a pull request or documentation without pulling in a full toolchain.
