BBCode viewer

The BBCode viewer accepts a BBCode string and outputs a sanitized HTML representation. It supports common formatting tags and ensures safe rendering for forums and CMS integrations. Its core logic focuses on parsing, validating, and converting BBCode into HTML while escaping potentially dangerous content. This tool is valuable to writers, editors, moderators, and developers who need reliable previews before publishing. It provides a consistent, deterministic transformation that can be integrated into content pipelines or used as a standalone preview utility. Real-world use cases include validating user-generated posts, previewing forum messages, and integrating BBCode rendering into web applications. The tool differentiates itself by combining strict safety, robust nesting checks, and an extensible tag mapping system that accommodates both standard tags and optional custom definitions. Core features include balanced tag verification, HTML output generation, and secure escaping. Optional features cover advanced tag attributes, nested lists, code block handling, and a mode to restrict unknown tags. The result is a predictable HTML representation suitable for publication or further processing in CMS workflows. This approach reduces manual review time, improves content quality, and supports teams migrating content from BBCode-based systems to HTML/CMS pipelines.
