How can you protect a worksheet from being edited?

Applying a password to a worksheet through the Protection option in the Review menu is an effective way to prevent edits. When you protect a worksheet in this manner, you can set specific permissions that restrict users from making changes to the content, formulas, or formatting of that particular sheet unless they enter the correct password. This feature is essential for maintaining the integrity of the data and preventing accidental or intentional modifications by users who should not have editing access.

Locking the computer, saving the workbook as a PDF, and hiding the worksheet tabs do not directly prevent edits to the worksheet itself. Locking the computer only secures access to the entire system and does not offer any specific protection for the workbook. Saving as a PDF converts the document to a fixed format that can’t be edited in the same way as a worksheet but does not protect the sheet during its original, editable state. Hiding worksheet tabs simply makes the tabs less visible but does not prevent users from editing the worksheet if they access it another way. Thus, password protection is the most effective method for securing a worksheet against unauthorized edits.
