📝 Code Formatters & Beautifiers

Professional code formatting and beautification tools supporting 50+ programming languages with intelligent indentation and customizable formatting rules.

Why Code Formatting Matters

Clean, consistently formatted code is essential for professional development, team collaboration, and long-term maintainability. Whether you're working solo or with a team, proper formatting makes code easier to read, debug, and modify, reducing errors and development time.

These beautifiers support 50+ programming languages and configuration formats, from common web technologies to specialized tools for blockchain development, scientific computing, and DevOps infrastructure. Each formatter understands language-specific syntax rules and applies consistent styling automatically.

What You Can Do Here

Unlike traditional online tools that upload your data to remote servers, everything here processes locally in your browser. This approach is faster, more private, and eliminates security concerns about sensitive information like API keys, passwords, or proprietary code leaving your device.

Web Development: Format HTML, CSS, JavaScript, TypeScript, React JSX, and Vue.js components with modern syntax support.

Backend Languages: Beautify Python, Java, PHP, C/C++, and dozens of other programming languages following industry standards.

Data & Configuration: Clean up JSON, XML, YAML, SQL queries, and configuration files for better readability.

DevOps & Infrastructure: Format Docker files, CI/CD workflows, server configurations, and deployment scripts.

Privacy & Processing

All code formatting happens locally in your browser using advanced parsing algorithms. The tools never send your code anywhere - everything processes on your device, making these utilities safe for handling proprietary source code, configuration files, and sensitive development work.
