Extract just the fields you need from Excel as JSON, with business context

Pass an Excel file along with 'upstream context' (business background) and 'downstream context' (output schema), and a local LLM reads the file and returns JSON in the requested shape. Pull dimensions and weight from a design spec Excel; pull part numbers and quantities from an order Excel - the same API handles both, and stays accurate even when sheet layouts vary. Built on FastAPI + openpyxl + Qwen3-VL.
