How to use this plugin?

[HaydenHu]

After installation, let me choose a json file, I don't have this file
kicad7.0.7
win10

[hstarmans]

Plugin works best with Kicad 6 and commit a7fe16f
So git clone the repository and git checkout a7fe16f
Install kicad 6, install the plugin in the plugin directory by copying the python file.
Generate the json file with one of the notebooks and import the generated json file with the plugin.

After creating the virtual environment, activate it. On windows activate.bat and activate are in /venv/Scripts/
Run jupyter notebook
Click on one of the *.ipynb files.
Click run all cells. It should generate a json. I renamed one to txt below so you can rename is to json.
