Apart from the change requests on the code, here are some general remarks:

• Should we also have a --prettify option in th export like you did for the import?
• don't forget to update the documentation in the readme for both commands (you can follow the format of the other commands)

Thank you!

Hi @Mavbraz, This PR has no activity since more than one year. Someone else proposed to finish the work (@zerock54). I will hand over this PR next week unless you plan and commit to work on it in the coming weeks.
Let us know.
Thanks!

* Should we also have a `--prettify` option in th export like you did for the import?

* don't forget to update the documentation in the readme for both commands (you can follow the format of the other commands)

Thank you!

I think it's more important having this prettify in the export command.
I'm going to include it as well. (It will have the shortcut "p" since it won't be used for the port flag anymore)

FYI: I also updated the commons-server to be able to prettify in other parts of Mockoon if necessary in the future.

It's still missing to update the README and add few tests to this PR.
I'll do both in the next few days.

This looks good.
I requested some changes as in the meantime I removed support for the legacy file format. You can remove these test cases, it should make the CI pass too.
Only the readme doc is remaining, and after that we are good to go!

Thanks for the changes!
It will be included in the November release.
