HTML Formatter

This code beautification utility restructures HTML markup applying consistent indentation, line breaks, and attribute ordering that transforms minified or inconsistently styled code into human-readable format following modern development conventions. The formatter parses HTML documents, recognizes element hierarchies, arranges nested tags with configurable indentation (2-space, 4-space, tabs), and aligns attributes for improved scannability. Users paste unformatted HTML receiving instantly beautified output with preserved functional behavior, toggle options controlling whitespace handling around text nodes, maximum line lengths, and self-closing tag formats. Batch processing handles multiple files simultaneously, integration with diff tools highlights formatting changes verifying no semantic alterations occur, and syntax error detection flags malformed markup requiring manual correction. Common applications include preparing minified production code for debugging, enforcing team coding standards through pre-commit formatting, improving readability before code reviews, or restructuring legacy templates for maintenance projects. The formatter supports modern HTML5 semantics, handles inline scripts and styles appropriately, and provides output compatible with linters and documentation generators.
