Question
📝 **Question:** Best structure for receipt OCR? 📋 Pick the right answer. 💡 **Hint:** Re-read the theory above if unsure.
A
Free-text prompt asking Claude to 'extract everything you can' and parse the resulting markdown table downstream with pandas.read_html
B
JSON-schema output mode with a strict Pydantic schema + per-field nullable + confidence score per field for human-in-the-loop routing.
C
Hardcode a stack of regexes on Claude's free-text output covering currency, dates, and line-item rows for each vendor format you support
D
Skip Claude entirely and run Tesseract OCR on the image — Claude doesn't read receipts well enough for production invoice processing
