j2o

Converter from Jupyter to Org file format without any dependencies.

Without this package your only alternative is to use nbconver or pandoc with 164 dependencies just to be able to convert simple JSON format.

TODO: make reverse convrter.

https://pypi.org/project/j2o/

Command line usage

usage: j2o myfile.ipynb [-w] [-j myfile.ipynb] [-o myfile.org]

Convert a Jupyter notebook to Org file (Emacs) and vice versa

positional arguments:
  jupfile_              Jupyter file

options:
  -h, --help            show this help message and exit
  -j JUPFILE, --jupfile JUPFILE
                        Jupyter file
  -o ORGFILE, --orgfile ORGFILE
                        Target filename of Org file. If not specified, it will
                        use the filename of the Jupyter file and append .ipynb
  -w, --overwrite       Flag whether to overwrite existing target file.

For Linux add this line to ~/.bashrc

  export PATH=$PATH:/home/youruser/.local/bin

How this works

1. Loops through "cells".
2. Extract "source"
3. add Org header and tail around source ("#+begin_src python …", "#+end_src")

• code cells: images
• Tested for nbformat: 4.2.
