Merged cells, multi-level headers, multiple tables per sheet, totals mixed in with data. You can't just dump them to CSV and call it done. LLMs handle the easy cases but fall apart on complex workbooks at scale.Our approach uses an agent-guided compilation pipeline that produces SQL-ready relational tables with full cell-level provenance.
