How this tool works
Implements client-side HTML to Markdown Converter operations. Parses HTML DOM elements, converting headings, emphasis tags, and anchor links into standard Markdown syntax specifically designed for a documentation team converts legacy html user manuals into clean, modern markdown files.
- Block & Inline Lexical Parsing: Deconstructs raw Markdown into block elements (containers, paragraphs, lists) and inline tokens (links, code, emphasis).
- AST Tree Compilation: Constructs an abstract syntax tree representing document hierarchy and validating balanced tag delimiters.
- Transformation & Stripping: Serializes AST nodes to clean semantic HTML5 markup or strips formatting to yield pure unformatted plain text.
- Sanitization & Preview: Sanitizes HTML output to prevent script injection vulnerabilities and renders responsive visual previews.

Limits and verification
HTML script tags and potentially malicious iframe elements in source markdown are sanitized to prevent XSS. Deeply nested lists or blockquotes are bounded to prevent call stack overflows.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.
