Keep your Excel data validation rules intact during everyday data entry and editing.
Kutools for Excel adds a protection layer to existing validation rules, helping prevent them from being changed or damaged by pasting, filling, dragging, inserting, or deleting—and blocking values that do not meet the rules.
Validate Protection is available from Kutools Plus in Excel, with options to enable protection and verify protected validation rules.
Keep using Excel Data Validation to define the rules. Then use Validate Protection to help preserve those rules, block invalid entries, and recover them if unexpected changes occur.
Pasting, filling, dragging, inserting, and deleting can accidentally change, clear, or damage validation rules. Validate Protection adds a safeguard around the rules already in your workbook.
Validation should apply to more than direct typing. When a typed, pasted, filled, or otherwise entered value does not meet the existing validation criteria, Kutools blocks the operation and shows a warning.
Use Validate Protection alongside Excel sheet protection. Cells can remain editable for data entry while Kutools helps protect their validation rules from paste, fill, drag, and other operations that could otherwise affect them.
If VBA, macros, other automation tools, or unexpected operations modify or clear protected validation rules, Verify Data Validation Protection can identify the affected ranges and restore the saved validation rules.
When enabling Validate Protection, you can set a password so other users cannot simply turn the protection off. The password is optional, but it is especially useful for important shared templates.

What to know before protecting Data Validation rules in Excel.
No. Create and test your rules with Excel Data Validation first. Validate Protection works on top of those existing rules to help keep them reliable and prevent invalid input.
Yes. Validate Protection can block pasted, typed, filled, or otherwise entered values that do not meet the existing validation criteria. It also helps prevent operations such as pasting, filling, dragging, inserting, or deleting from damaging the validation rules themselves.
Yes. Disable Validate Protection first, make the required changes with Excel Data Validation, and then enable Validate Protection again so the updated rules become the protected rules.
Use Verify Data Validation Protection. Kutools can compare the current worksheet with the saved protected data, list affected ranges, and restore the original validation rules when differences are detected.
Restoring the validation rules does not automatically correct values that are already in the affected cells, so those values should still be reviewed.
Yes. Validate Protection can be used when worksheet protection is enabled. This is useful when validation cells are intentionally left editable for data entry but still need protection from operations that could damage their validation rules or introduce invalid values.
The protection remains effective for recipients only when Kutools for Excel 35.00 or later is installed on their computer. Without a supported Kutools installation, the workbook's validation rules and protected data may not be fully safeguarded from modification or damage.
