Use case
Help Excel users repair one formula that is not recalculating, not updating after source-cell changes, displaying as formula text, or returning a stale value after a workbook setting, import, copy, or formula edit.
Use this page when an Excel formula does not calculate automatically, returns an old value after source cells change, only updates after a manual recalculation, or displays the formula text instead of the result. It is strongest when you can paste the formula and name one expected result.
Do not assume the formula itself is wrong before checking workbook calculation mode, Show Formulas, and cell formatting. Those settings can make a correct formula look broken, and changing the formula first can hide the real cause.
A review flag can look stuck when Excel is in manual calculation mode or when the referenced revenue cell was imported as text.
=IF(VALUE(B2)>1000,"Review","OK")
The formula converts B2 to a number before testing the threshold. Use it only after checking that B2 should contain a numeric value and that workbook calculation settings are not the actual blocker.
