Jupyter Notebook Execution Count Reset

This free online tool fixes out-of-order In [n] execution counts in Jupyter .ipynb notebooks without re-running any cells. Download the fixed files with a -fixed.ipynb suffix.

• You keep your existing outputs and you do not need to run the cells again.
• This helps when the notebook already took hours to run, and rerunning everything is not practical.
• Everything runs in your browser and your notebooks are not uploaded or saved on a server.
