Drop .ipynb files in, get their Python source out. Runs entirely in the browser — no upload, no build step, no dependencies. Open notebook-to-python.html and go.
Built for pasting notebooks into an LLM, so it optimizes for that: token counts up front, tracebacks preserved, one button to copy everything.
