How Do I Use Data Validation To Restrict The Values That Can Be Entered Into A Cell?

To use data validation to restrict the values that can be entered into a cell in Google Sheets, follow these steps:

  1. Select the cell or cells where you want to apply the data validation.
  2. Click the “Data” dropdown in the toolbar, then select “Data Validation.”
  3. In the “Criteria” section, choose the type of validation you want to apply from the dropdown menu. For example, you can choose “Number” to only allow numerical values, or “Date” to only allow dates.
  4. Depending on the type of validation you chose, you may need to enter additional criteria. For example, if you chose “Number,” you can specify a minimum and maximum value.
  5. If you want to show an error message when an invalid value is entered, check the “Show a warning when the value is invalid” box and enter the desired message in the “Value” field.
  6. Click “Save.”

Your data validation will now be applied to the selected cell or cells. When a user attempts to enter a value that does not meet the criteria, they will see an error message and will not be able to save the invalid value.
