Markdown → Jupyter Notebook

Any fenced code block ( python.. ) in your Markdown becomes a code cell in the output notebook. All other content, headings, paragraphs, lists, images, becomes Markdown cells. The language tag on the fence (python, r) sets the cell's kernel hint.

Yes. Code blocks fenced with `python become runnable code cells. You can open the.ipynb in JupyterLab, VS Code, or Google Colab and execute them immediately. The converter does not execute the code, it only converts the structure.

Yes. Standard GitHub-flavored Markdown from any source works, Obsidian, Notion exports, Typora, HackMD, Bear, and others. As long as code blocks use standard triple-backtick fencing, the converter will detect them correctly.

Headings (#, ##, ###), bullet lists, numbered lists, bold/italic text, and Markdown tables are all preserved as Markdown cells inside the notebook. They render correctly when the notebook is opened in Jupyter or VS Code.

Yes, paste or upload your README.md and the converter builds a notebook from it. Code examples in the README become runnable cells. This is a great way to turn documentation into an interactive tutorial or workshop.

Jupytext is a command-line Python library requiring installation. This tool runs in your browser, no Python, no pip install, no terminal needed. Jupytext also handles round-trip sync (notebook ↔ Markdown); this tool focuses on the one-way MD to IPYNB conversion for users who want a quick, zero-setup option.

Yes. Code blocks fenced with r, julia, `sql, or any other language tag are preserved in the notebook. However, to execute non-Python cells, you'll need the appropriate kernel (R kernel, IJulia, etc.) installed in your Jupyter environment.

The converter detects the most common language from your code block tags and sets the notebook metadata accordingly. You can also change the kernel in JupyterLab after opening the file via Kernel to Change Kernel.

Images referenced by URL will appear correctly when viewed with an internet connection. Locally referenced images (![alt](./image.png)) will appear as broken links unless you re-embed them. For offline use, consider hosting images before converting.

Yes, it is the exact reverse workflow. If you exported a notebook to Markdown earlier, you can re-import it here to get a clean.ipynb back. This makes it easy to edit notebooks as plain text in any editor and then reconvert.

Yes when the page offers a paste area. Paste UTF-8 Markdown from any editor, preview the cell split, then download the .ipynb.

Prefer fenced triple-backtick blocks with a language tag. Indented code may stay inside Markdown cells depending on detection; fences are the reliable path for executable cells.
