Hello,
I have such kind of work earlier, to convert EDI request in a format which seller or buyer system support, I have worked on many EDIs like GCOMMERCE, TRUECOMMERCE, NEXT PART, PARTSTECH, used IPO etc.
I have worked a lot on CSV file, they send request data in xml or other format, I have convert it in CSV format and make sales order and send back response in format which I received in request.
In short I can do this project very well, let's connect.
Waiting for your information.
