Jupyter Notebook are the perfect playground for every nerd. The documents are based on JSON, but they follow a versioned schema, and contain ordered lists of input/output cells which can contain code, Markdown text, mathematics, plots and rich media. See what I mean? Jupyter Notebook provides a browser-based interactive interface that let’s you make those files. The whole Jupyter universe is huge. But you’re here, so I suppose you already know more about this stuff than me. You’re probably only looking for a nice and free converter and what should I say? I’ve never used Jupyter, but I built this free online converter you’re looking for. Happy converting!
