Quick answer
A validation message can mean the cell intentionally accepts only specific values. Read the rule before changing the workbook or assuming Excel is damaged.
Understand the issue
Examples include a list of approved departments or a number range. The visible cell format does not tell you the complete validation rule. Preserve the rejected value separately while checking what the workbook expects.
Step-by-step checks
- Read the full validation message.
- Inspect the affected cell's Data Validation settings.
- Enter an allowed test value or ask the owner to revise an incorrect rule.
