Hello,
I am from the Loadium team. Sorry for the inconvenience, It might be a network problem or something when you guys tried to use our free converter service at that time. If it happens again please don’t hesitate to contact Loadium support at any time. The Loadium Converter is a free and 7/24 available service, besides it’s an open-source project. You may also freely clone this repository https://github.com/Loadium/postman2jmx and use the converter locally, and please don’t forget to star this repository.
