Split Jupyter notebook online — break one .ipynb into multiple valid notebooks in your browser
When you need to split jupyter notebook online for smaller hand-ins, separate lessons, or repo hygiene, this tool turns one `.ipynb` into several nbformat files you can download in one ZIP. It targets searches like split ipynb file, split jupyter notebook into multiple files, and ipynb file splitter—without `nbconvert`, Pandoc, or a local Python stack on the machine you have right now. Parsing stays in your tab: nothing is uploaded to split the notebook.
Students ask how to split a jupyter notebook when one semester-long file becomes impossible to review; teams split ipynb file artifacts before attaching cells to different tickets. Choose pro-style rules: split at Markdown headings (`#` for chapters or `#` + `##` for sections), or slice every *N* cells for predictable chunk sizes. Toggle execution hygiene—clear `In [n]` labels or renumber them inside each part—plus pretty-printed JSON for readable archives.
