Use library to convert json files to footprints/symbols

It would be nice to be able to use the library for converting json files exported from easyEDA to create footprints and symbols for kicad.
This would also help developing the code since its possible to create custom footprints for testing.

I am not sure to understand what you mean, could you give me more details please ?
Xyntexx commented
Instead of creating Kicad libraries using the JLCPCB part number the same code could be used to convert footprints exported from the EasyEDA editor online. The export option produces a JSON file that uses the same format as the JSON fetched from the library.
Here is how to export a footprint from EasyEDA
Here is the JSON code from the footprint above

I haven't needed to import custom or user-contributed footprints from EasyEDA other than for potentially debugging for this library but it could be achieved with low effort.
TousstNicolas commented
I understand the usefulness of this feature for debugging.
However, I don't see a practical use case for it and implementing it would add unnecessary complexity to the script. As you mentioned, you have not personally needed it in the past.
I will be closing this issue as it is out of the scope of the current project. If anyone else feels that they have a compelling use case for this feature and finds this issue, they are welcome to reopen it and provide their reasoning.
Thank you
