I’ve seen this exact workflow (PDF → extract data → update structured files) come up a lot, and it’s impressive that Claude handled it end-to-end like that.
We’ve been building Retab.com to handle those kinds of tasks more reliably, especially when you want structured output (like JSON) from messy documents like PDFs, scans, or even images.
Instead of writing ad-hoc scripts or chaining LLM calls, you just upload the file, define what you want (via schema), and it gives you clean structured data. It’s AI-native but deterministic, no need to install PyPDF2 or debug model behavior.
Just wanted to share in case others are solving similar problems repeatedly.
