Spreadsheet Reverse Engineering Studio

 Build a spreadsheet reverse-engineering studio that explains how an unfamiliar workbook actually works. Analyze formulas, named ranges, hidden sheets, input cells, lookup tables, dependencies, macros where accessible, and relationships between outputs. Generate an interactive map of the workbook's logic, explain important calculations in plain English, identify fragile assumptions and hardcoded values, and let users trace any output back to its source. Include a safe sandbox for changing inputs and observing downstream effects without altering the original workbook.
