auto fill not working due to data validation restriction

If the Auto Fill feature in Excel is not working for a specific range due to data validation restrictions, here are a few steps you can try to resolve the issue:

Autocomplete not working for data validation

1. Check data validation settings: Double-check the data validation settings for the problematic range. Ensure that the criteria and settings are correctly applied. Pay attention to any constraints or custom formulas that might be causing the restriction.
2. Disable error alerts: Sometimes, error alerts associated with data validation can interfere with the Auto Fill feature. Temporarily disable the error alerts by going to "Data" tab > "Data Validation" > "Data Validation" button, and uncheck the "Show error alert after invalid data is entered" option. This will prevent any error messages from appearing when using Auto Fill.
3. Clear existing data: If there is already data within the range affected by data validation, try clearing it before attempting to use Auto Fill. Right-click on the range, choose "Clear Contents," and then try using Auto Fill again.
4. Use a workaround: If Auto Fill still doesn't work, you can try a workaround by copying the values from a nearby cell that doesn't have data validation applied and then pasting those values into the problematic range. This will bypass the data validation restrictions.
5. Re-create the data validation: If none of the above solutions work, you can try deleting the existing data validation for the range and recreating it. Remove the data validation by selecting the range, going to "Data" tab > "Data Validation" > "Data Validation" button, and choose "Clear All." Then, reapply the data validation settings and test Auto Fill again.
6. Test in a new workbook: If the issue persists, try testing the Auto Fill feature and data validation in a new, blank Excel workbook. This can help determine if the problem is specific to the current workbook or if it is a more general issue with Excel.

If the problem continues to occur despite these steps, please provide more specific details about the data validation settings and any error messages encountered.

Specific details such as Excel version, operating system, storage medium, etc.
