About this tool
Paste Markdown to extract every backtick or tilde fenced code block without executing its contents. Review its language, character and line counts, then copy or download individual files or one bulk Markdown file.
Questions & answers
- Does this tool run the extracted code?
- No. Code is displayed as plain text and is never evaluated or sent to a server.
- How is the download extension chosen?
- A small local mapping recognizes common fence languages such as TypeScript, Python, JSON, and CSS. Unknown or missing languages use .txt.
- What does the bulk export contain?
- It contains all extracted blocks as fenced Markdown, using a fence long enough to preserve backticks found inside the code.
