AI and Financial Model Cleanup: Refactoring an Inherited Spreadsheet
AI can suggest formula audits and structure improvements; you still walk every link before trusting it.
11 min · Reviewed 2026
The premise
You inherited a financial model with 47 tabs, hardcoded numbers in formulas, and one critical error from 2019 nobody caught. AI can audit structure, surface inconsistencies, and recommend a clean rebuild plan — without ever fully understanding your business.
What AI does well here
Identify hardcoded values inside formulas.
Flag inconsistent formulas across rows or columns.
Suggest a tab structure consistent with FAST or SMART standards.
Draft the rebuild plan and the testing protocol.
What AI cannot do
Open and execute the actual workbook (most can't).
Know your business logic well enough to validate calculations.
Replace the cell-by-cell rebuild that complex models require.
