Validate, format, minify, and explore JSX components — with React-specific linting, strict syntax checking, and symbol navigation.
Transform messy JSX into clean, readable, and well-structured code with a single click. The formatter automatically fixes indentation, spacing, line breaks, and component structure, making your React code easier to read, maintain, and share.
Catch JSX and React syntax errors as you write. The validator highlights issues such as unclosed tags, missing brackets, invalid attributes, and other common mistakes, helping you fix problems before compilation.
Identify common JSX and React issues such as unused variables, duplicate declarations, invalid component usage, and other potential problems. Clear warnings help you find and resolve issues quickly.
Format and analyze modern React and JSX features, including functional components, hooks, fragments, conditional rendering, JSX expressions, arrow functions, and ES6+ syntax.
View useful information about your JSX code, including component counts, functions, variables, imports, exports, nesting depth, and file size statistics for original, formatted, and minified code.
Navigate your code using a structured list of components, functions, methods, and other important symbols. Jump directly to any definition and explore large React files more efficiently.
Customize formatting preferences such as quote style, indentation size, semicolon usage, and JSX formatting rules. Apply consistent styling across all your React projects.
Reduce the size of your JSX and JavaScript code by removing unnecessary spaces, comments, and formatting. Generate a compact version of your code while preserving functionality.
const Card = ({title,text}) => {return (<div className="card"><h3>{title}</h3><p className="muted">{text}</p><button onClick={()=>alert('click')}>Ok</button></div>)}Clean up messy JSX and React components with a single click. The formatter automatically fixes indentation, spacing, line breaks, and component structure, making your code easier to read, maintain, and share with other developers.
Check your JSX code for common issues such as unclosed tags, invalid attributes, missing brackets, and syntax errors. The validator highlights problems instantly, helping you fix mistakes before running your application.
Use the Symbol Explorer and Statistics Dashboard to better understand large React components. View component structures, navigate functions and methods, and analyze code metrics to make development and maintenance easier.
Paste your JSX code into the editor, upload a local file, or load code from a URL. The editor instantly displays your code and prepares it for formatting, validation, analysis, and minification.
The tool scans your JSX and React code to check for syntax errors and common issues. Any problems found, such as unclosed tags or invalid JSX syntax, are highlighted with clear warnings so you can fix them quickly.
Select formatting options such as quote style, indentation size, JSX formatting rules, code transformations, and minification settings. The tool automatically applies your chosen preferences to keep your code clean and consistent.
Review the formatted code, statistics, and symbol information. You can copy the output, download it as a file, or use the minified version for production. All processing happens locally in your browser for better privacy and security.
JSX formatting organizes your React code by fixing indentation, spacing, line breaks, and component structure. This makes your code cleaner, easier to read, and simpler to maintain.
Yes. The formatter works with React hooks such as useState, useEffect, useMemo, useCallback, and other modern React features.
Yes. The tool formats JSX code that contains Tailwind CSS classes, helping keep long className values organized and easier to read.
Yes. The tool is designed for React and JSX files, making it useful for formatting, validating, and analyzing React components.
No. Formatting only changes the appearance of your code, such as spacing and indentation. Your component logic and functionality remain unchanged.
No. All formatting, validation, analysis, and minification happen directly in your browser. Your code stays on your device and is never uploaded.
Formatting makes React components easier to read, debug, and maintain. It also helps keep a consistent coding style across your project.
Self-closing tags are JSX elements that do not have child content, such as img, input, and br. They are written with a closing slash, for example: <img src="image.png" />.
The Statistics Dashboard displays useful details such as component counts, functions, variables, imports, exports, nesting depth, and code size information.
Yes. The minifier removes unnecessary spaces, comments, and formatting to create a smaller and more compact version of your code while keeping the same functionality.
