I've just stumbled across this post. I am an aspiring developer and one of my first few projects is a HL7 v2 message generator. It takes in a message template and then you can edit and create bulk messages from it.
Simply choose which segment to edit, specify the field position and then you can add a CSV of values. test, test2 and so on. You can choose to download the messages or display them in your browser. It also provides a JSON file showing you which new values are grouped. Not sure of all the use cases but I built it for a bit of fun over a weekend!
