# Financial Model QA ## What this does Audits a spreadsheet financial model for formula errors and logic defects, and re-checks scenario outputs after inputs change. It produces a ranked list of issues, each pinned to an exact sheet and cell. It flags problems for you to review. It does not fix anything and never writes to the workbook. Think of it as a careful reviewer that points at every suspect cell and explains what looks wrong, leaving every change to you. ## When to use it - Before you share a model with anyone, or before a number from it drives a decision. - After you edit inputs, assumptions, or structure and want to confirm the scenarios still flow through correctly. - When you inherit a model you did not build and need a map of where it is fragile. ## Inputs — how to give it the data - **Default:** hand over the model workbook directly — drag in the file, attach it, or paste a path. A spreadsheet (.xlsx and similar) is the expected input. - **Optional prior version:** include the previous version of the same model and the skill will diff the two, so you see what changed and whether the change behaved. - **Multiple files / linked workbooks:** if the model pulls from other files, say so and provide them. If a referenced file is missing, the skill flags the broken external link by cell rather than guessing what it pointed to. - **Lossy or partial exports:** if the file is a flattened export with formulas stripped to values, the skill can only check t
