How can you protect a worksheet in Excel?

Protecting a worksheet in Excel primarily involves restricting access to certain functions or content within that worksheet to prevent unintended changes. The most direct method to ensure this protection is by setting a password under the Review tab. When you choose to protect a worksheet, it allows you to specify what users can and cannot do, effectively safeguarding the data.

Setting a password means that anyone attempting to modify the worksheet will need to enter the password, providing a robust level of security. This is particularly useful in collaborative environments where multiple users might have access to the file, ensuring that only authorized individuals can make changes.

While other methods such as hiding the worksheet can obscure it from view, this does not prevent users from unhiding and making changes. Using the Data tab options or converting to Read-Only format serves different purposes outside of worksheet protection; they focus on other aspects of data management or access but do not offer the security of requiring a password to edit the sheet directly.
