That's not very likely to succeed, is it? LLMs can do a lot of things, but writing software that not only parses semi-proprietary file formats but also analyze unstructured data sounds more than little bit far fetched. I'd be impressed if just the first, and by far the easiest, part of that can be accomplished.
It's extremely likely to succeed because there is a documented format. I can't believe how pessimistic this site is about this stuff. Yeah, you're not going to one shot it with a prompt. If that's your expectation, you're confused.
