HTML Unescape Tool for Config Files

About This Tool

Configuration files are at the heart of modern software development — from package.json and tsconfig.json to VS Code settings and cloud infrastructure templates. This HTML Unescape Tool for Config Files is tailored for processing HTML configuration files with the precision and care they require. Configuration files often contain comments (in formats that support them), version-specific settings, and carefully structured hierarchies that must be preserved during formatting. The tool processes these files while maintaining all data integrity, ensuring that indentation reveals the logical structure of configuration sections, nested settings, and conditional values. Whether you are cleaning up auto-generated configuration, merging settings from multiple sources, or preparing config files for documentation, this tool handles the task reliably.

What is HTML Unescape Tool?

An HTML unescape tool converts HTML entities back to their original characters. It decodes standard entities like &amp; → &, &lt; → <, &gt; → >, &quot; → ", and numeric/hex entities like &#39; → ' and &#x2F; → /. This is useful when processing HTML content from APIs, databases, or CMS systems where text has been double-encoded or when you need to extract the original text from HTML-encoded strings. Web scraping, content migration, and data processing frequently encounter HTML-encoded text that needs to be decoded before further processing or display in non-HTML contexts.

How to Use This Tool

1. Paste HTML-escaped text.
2. Click Unescape HTML.
3. View the decoded characters.
