Also to easily import and export things.
Use @davorpa code mentioned here. (direct link)

And for importing just install "Settings" app (link) by probot and make this file :
.github/settings.yml

# Labels: define labels for Issues and Pull Requests
labels:
- name: api
  description: This issue or pull request is related to API
  color: b60205
- name: not related
  description: not related to us or our plugins/addons
  color: d93f0b
- name: awaiting response
  description: Waiting for response

Happy importing. And thanks to @davorpa for both json and yml / yaml file saver.

A pleasure. Thanks for mention ❤❤❤

@davorpa Well, it's thanks to you for making exporter from js and without installing any software or packages and adding tokens (sharing tokens is always scary) in PC to get them.
