HTML Formatter/Validator

HTML (HyperText Markup Language) is the foundation of the web. However, as web applications grow in complexity, HTML code can quickly become a tangled mess of nested tags and attributes. Our HTML Formatter/Validator is a professional tool designed to bring order to your markup. It parses your HTML input and transforms it into a clean, hierarchical structure with consistent indentation and line breaks. This makes it much easier to understand the relationship between elements and to identify structural issues. The built-in validator is particularly useful for catching common errors like unclosed tags, which can cause significant rendering issues in browsers. By using this tool, you can ensure your HTML is clean, readable, and follows the latest web standards.

Paste your raw or minified HTML code into the editor. Click "Format" to apply consistent indentation and line breaks. The tool will validate your HTML against standard rules, highlighting any unclosed tags or invalid attributes.

For web developers, clean markup is essential for maintainability and debugging. Our HTML Formatter/Validator provides instant clarity, allowing you to quickly navigate through complex layouts and identify issues. It's an invaluable tool for anyone working with modern web frameworks, where HTML is often generated dynamically. The real-time validation pinpointing exact line numbers where a tag is missing or an attribute is invalid saves significant time and frustration. Furthermore, because this tool runs entirely in your browser, your proprietary markup and sensitive data never leave your machine, providing a secure environment for managing your most critical web assets.
