How to create JSON file from postman collection(s)

Question

I want to convert my current Postman collection(s) to JMeter jmx files

I should be able to convert in loadium by adding collection JSON file, But I don't find Export option anymore (even I'm sign in to postman), was it removed ?

How/where collection JSON are saved?

I didn't find a valid answer here (sharing) or here (Postman uses LevelDB)

If you just need to export your collection, this might help.
