Can I use data validation in Google Sheets?

Yes, Google Sheets provides a feature called Data Validation that allows you to control the type and range of data that users can enter in a cell. This is particularly useful when you're sharing a sheet with others and want to ensure that the data entered is consistent and accurate.

To use data validation in Google Sheets, first select the range of cells where you want to apply it. Then, go to the Data menu and click on 'Data validation'. From there, you can choose the criteria for the data validation, such as numbers only, a list of specific values, or a custom formula. You can also specify an error message to display if the user enters data that doesn't meet the validation criteria.

Data validation can save you a lot of time and effort in the long run by preventing errors and inconsistencies in your spreadsheets. It's a simple but powerful tool that every Google Sheets user should know how to use.
