AI Data Flows Privacy Audit: Notebook Files

Two main types of files exist for notebooks:

  • ipynb used by Jupyter
  • .py files used by marimo

This analysis focuses on the ipynb files.

ipynb files are json files that contain the code and data for a notebook. They also contain the metadata for the notebook as well as the output of the cells.

Tools like nbstripout can be used to remove output from ipynb files. Tools like nbconvert can be used to convert ipynb files to .py files. Tools like papermill can be used to run notebooks with parameters.
