Data validation acts as a gatekeeper for your spreadsheets, ensuring that only acceptable data is entered. It helps maintain data integrity and saves time on cleaning up incorrect entries.
Steps to Add Data Validation
1. Select the Cells
First, highlight the cells where you want to apply data validation rules.
2. Access Data Validation

- Criteria: Choose the type of validation you want to apply. Common options include:
- Number: Restricts input to numerical values. You can specify minimum and maximum values, allow whole numbers only, or define a custom formula.
- Date: Limits input to valid dates within a specified range.
- List: Allows only predefined values from a list you create.
- Text Length: Sets a minimum and maximum character limit for text entries.
- Custom formula: Use a Google Sheets formula to define complex validation rules.
- Allow: Select whether to allow “blank” entries, “input” (free text), or “only from list” entries.
- Show error alert: Choose the type of error message to display if a user enters invalid data. Options include “Stop,” “Warning,” or “Information.”
- Error message: Customize the message that appears to the user when they enter invalid data.
4. Save the Validation
Click “Save” to apply the data validation rules to your selected cells.
Example: Validating Email Addresses
Let’s say you want to ensure that users enter valid email addresses in a specific column. Follow these steps:
- Select the column containing the email addresses.
- Go to “Data” > “Data validation.”
- Under “Criteria,” choose “Custom formula.”
- In the formula box, enter: `=REGEXMATCH(A1, “[^@]+@[^@]+.[^@]+”)` (Replace “A1” with the first cell in your selected range). This formula checks if the email address follows a basic pattern.
- Set the “Allow” option to “input only” to prevent blank entries.
- Customize the error message as needed.
- Click “Save.”
Recap
Data validation in Google Sheets is a valuable feature for maintaining data accuracy and consistency. By defining validation rules, you can control the type of data entered into your spreadsheets, prevent errors, and save time on data cleaning. Remember to choose the appropriate criteria, allow options, and error messages to suit your specific needs.
