HTML Decode String

This text processing utility converts HTML entities back to their original character representations, handling over 200 named entities plus numeric character references. The decoder processes common entities like & < > alongside currency symbols (€ £), mathematical operators (± ×), Greek letters (α ω), diacritical marks (é ñ), and special punctuation (— …).

Named entity decoding maps standard HTML entity names to Unicode characters using a comprehensive lookup table covering W3C specifications. Numeric entities support both decimal (<) and hexadecimal (<) formats through pattern matching that extracts code points and converts them to characters via String.fromCodePoint(). The bidirectional interface toggles between decode mode (entities to characters) and encode mode (characters to entities) for flexible text processing.

Real-time conversion updates output as you type, with statistics showing character counts and entity detection. Common applications include cleaning web-scraped content, parsing escaped HTML for display, processing API responses containing encoded characters, and preparing text for systems that don't support raw Unicode. All processing executes client-side ensuring complete privacy for sensitive content manipulation.
