Converting .py files to .ipynb

Question

My organisation converts any Jupyter Notebooks (.ipynb files) it makes into python scripts (.py files) for easier management in our repos. I need to convert them back so I can run the notebooks but can't work out how.

I believe they've been encoded using the nbconvert package but I couldn't find a way to convert the files back in the package docs.

I've included the head of one of the .py files bellow in case it makes the encoding format more obvious.

# jupyter:
#   jupytext:
#     formats: ipynb,py:light
#     text_representation:
#       extension: .py
#       format_name: light
#       format_version: '1.4'
#       jupytext_version: 1.2.0
#   kernelspec:
#     display_name: Python 3
#     language: python
#     name: python3

Looks like the file was actually converted using program jupytext.

To convert it back I found running jupytext --to ipynb my_file.py worked.

More simply: opening the .py file in jupyter notebook aloud me to view the .py file as if it were a .ipynb file without converting.
