About Markdown Code Block Extractor

Fenced code blocks in Markdown are delimited by triple backticks (```) optionally followed by a language identifier. This tool parses your Markdown and extracts every fenced block, showing the language tag, line count, and the raw code content. Useful for pulling code snippets out of documentation, README files, or tutorial posts without manually scanning the source. Inline code (single backtick) is intentionally ignored — only fenced blocks are extracted.

Private & free — this tool runs entirely in your browser.
