5 Common Reasons For "This Value Doesn'T Match The Data Validation" Error In Excel

When working with Excel, you might have encountered the frustrating error message: "This value doesn't match the data validation." This error can arise for various reasons, causing inconvenience, especially when you are knee-deep in analyzing data. Understanding why this happens is crucial for troubleshooting and efficiently managing your spreadsheets. In this blog post, we will explore the five common reasons for this error and provide you with practical tips and tricks to overcome them. 🚀

Understanding Data Validation in Excel

Data validation is an essential feature in Excel that allows users to control what data can be entered into a cell. It helps in maintaining data integrity and ensures that only valid entries are made. However, this robust feature can also lead to a few hiccups if not correctly set up. Let's dive into some common reasons why you might encounter the "This value doesn't match the data validation" error message.

1. Mismatched Data Type

One of the most common reasons for this error is a data type mismatch. For instance, if a cell is set up to only accept numbers, but a user tries to enter text or a mix of characters, the validation will fail.

Example: If a cell is validated to accept only whole numbers and someone tries to input "5.5" or "hello," Excel will throw an error.

2. Invalid List Items

Using the list feature in data validation is handy but can cause issues if the entries are not matched correctly. If the list has been changed and the new entries do not match those in the validation rule, the error will appear.

How to Check:

• Go to the cell with the error.
• Click on "Data Validation" under the "Data" tab.
• Check the source list and ensure all items are valid.

3. Hidden Characters or Spaces

Sometimes, hidden characters, leading spaces, or trailing spaces can lead to unexpected validation errors. This can be particularly troublesome when copying and pasting data from different sources.

Tip to Fix:

• Use the TRIM function to remove unnecessary spaces.
• Example: =TRIM(A1) will clean up any spaces in cell A1.

4. Formulas in Validation Criteria

If you use a formula in your data validation settings, it’s crucial to ensure the formula returns the correct data type and values expected. If the formula is misconfigured or returns an incorrect output, you'll encounter the validation error.

Common Mistake:

• Using a formula that checks for conditions but returns an array of values instead of TRUE or FALSE.

5. Protected Sheet

Another sneaky cause of the validation error can be a protected worksheet. If your sheet is protected and the data validation rules do not allow certain changes, it can lead to errors.

Check Protection Settings:

• Go to the "Review" tab, and see if the "Unprotect Sheet" option is available. If it is, the sheet is protected.

Troubleshooting Tips

To effectively troubleshoot the "This value doesn’t match the data validation" error, here are some additional strategies:

• Clear the Cell: If you're consistently getting an error, try clearing the contents of the cell and re-entering the value.
• Modify the Validation Rule: You may want to revisit the data validation settings and make any necessary adjustments.
• Examine Source Data: Always ensure that the data you're referencing in your validation lists or formulas are accurate and correctly formatted.

Common Mistakes to Avoid

• Over-complicated Validation Rules: Keep your validation rules simple to avoid errors.
• Copying and Pasting Data: Always check for data integrity when copying data from other sources.
• Neglecting to Update Validation Rules: If data in your reference lists changes, make sure to update your validation rules accordingly.

Practical Example

Imagine you're managing a team roster in Excel where you need to ensure that team members' positions are selected from a predefined list. If someone accidentally enters a position that's not on the list, they will face the dreaded validation error. To prevent this, always verify that the validation list is current and reflects all possible entries.
