Three findings you can reproduce
The fictional Audit Demo worksheet deliberately contains a broken margin calculation and an overwritten forecast formula. It follows the example in our documented Excel audit walkthrough, which includes captured requests and findings.
| Cell | Finding | Review and correction |
|---|---|---|
| D5 | =D4/0 produces #DIV/0!. | Margin should be profit / revenue. =D4/D2 gives 70 / 165 = 42.4%. |
| D6 | The value 999 replaces a formula. | With the same 10% growth assumption as adjacent quarters, =D2*1.1 gives 181.5. |
| B6, C6, E6 | The growth factor 1.1 is embedded in formulas. | Confirm the assumption. Move it to a labeled input if it needs to be maintained centrally. |
Amounts are USD thousands. Expected results describe this exercise, not guaranteed findings for every workbook. Checking the formula's business meaning remains part of the review.
