If you use the excellent Postman for testing and developing your APIs (and if you don’t yet, please give it a try!) you may find this little node script helpful when generating documentation.
It simply converts your downloaded Postman collection file to HTML (with tables) for inserting into documentation or sharing with a 3rd party developer. The Postman collection is perfect for sharing with developers as it remains close to “live documentation”, but sometimes you need a more readable form.
