[Improvement] Export collections using Postman format

Insomnia supports exporting collections in the Insomnia and HAR formats. I would like to add the ability to export using the Postman collection format(s).

I have spent a lot of time building an extensive collection in Insomnia that would be of great use to others in my organization, but most of them use Postman, and currently there is no way to export collections to a Postman-compatible format. I have no intention of making it more attractive for people to use Postman (quite the opposite in fact), but this would be a useful feature that would allow teams to use the REST client of their choice while still being able to share collections.

Documentation for the various Postman collection JSON schemas can be found at

If this is something you think would be useful, I would be happy to implement it in my spare time and open a PR.
