How can you secure a worksheet from being edited?

To secure a worksheet from being edited, protecting the worksheet with a password is the most effective method. This action prevents unauthorized users from making changes to the worksheet's contents, including cells, formulas, and formatting. When a worksheet is protected with a password, users must enter the correct password to unlock editing capabilities, ensuring that the integrity of the data is maintained.

Other options, such as changing the color of the text, hiding rows and columns, or removing formulas, do not provide real security. Changing the color of text simply alters its appearance and does not prevent editing access. Hiding rows and columns can be easily reversed and does not restrict users from editing visible or hidden content. Similarly, removing formulas might hide calculations, but it does not provide any protection against edits, as users can still modify any elements in the worksheet. Thus, using a password is the primary method for effectively securing a worksheet.
