Spreadsheet Model Auditor

Audits business spreadsheet models (.xlsx, .xlsm, or Google Sheets exported to .xlsx) for structural integrity errors and explains each fix -- budgets, forecasts, pricing models, commission calculators, FP&A packs, ops trackers, not only banking models. A bundled openpyxl script finds hardcoded numbers inside formulas, typed values pasted over formulas, inconsistent formulas across a row or column, #REF!/#DIV/0!/#N/A errors, circular references, SUM ranges that skip adjacent rows, totals that do not foot, whole-column ranges that double count, external links, volatile functions, and hidden sheets/rows, each with a cell address and severity. Use this whenever the user says "check my spreadsheet", "audit this model", "review this workbook", "why doesn't this total match", "is this forecast right", "sanity check my budget", "find errors in this Excel", or shares an xlsx/Sheets file and asks whether the numbers can be trusted, even if they never say "audit".
