Why Excel formulas stop working
Most Excel formula errors come from data quality or workbook structure rather than the formula itself. Ecommerce exports often contain extra spaces, currency symbols, phone numbers formatted as text, or inconsistent order statuses. Accounting sheets may have deleted columns, missing invoice numbers, or blank denominator cells. HR sheets often mix real dates with text dates.
This Excel formula debugging tool helps you work through the problem systematically. Select the error, read the cause list, copy a safer formula pattern, and then check the source data. If the formula uses lookups, verify both lookup value and lookup range. If the formula uses percentages or dates, confirm that Excel recognizes the values as numbers or dates.
If the syntax is correct but the formula still returns the wrong result, use the Excel Formula Explainer to inspect its arguments. When you need a clean formula for a new task, start with the Excel Formula Generator.
