Runs formula audits on spreadsheets with three scope levels: selection, sheet, or full model. The selection and sheet scopes catch common mistakes like hardcoded values in formulas, off-by-one sum ranges, and inconsistent formulas. The model scope is where it gets serious. It identifies whether you're working with a DCF, LBO, or 3-statement model and runs integrity checks specific to that type: balance sheet balancing, cash tie-outs, circular reference validation, and model-specific bugs like terminal values not being discounted back or debt paydown mechanics breaking in an LBO. Reports findings in a severity table without making changes. If you send financial models to clients or investment committees, this catches the silent errors that make you look incompetent.
