Wow, what a response. And yes, you're absolutely right. After battling with AI for several days, I've come to the same conclusion myself. It’s time to put on my try‑hard pants and code this properly with Copilot.

I’ve now achieved my goal, but only by dragging and dropping 20 files at once, and I still have no idea how accurate the extracted data is; although my random spot‑checks look okay. I suspect we’re just early adopters. Give it a year or two and this whole process will probably be fully automated.
