Final answer:
To allow other users to manipulate certain cells in a worksheet, those cells should be left unprotected. By doing this, other cells can remain locked for security, while the unprotected cells can be edited.
Step-by-step explanation:
If you wish to allow another worksheet user to be able to manipulate some cells, leave those cells unprotected. Worksheet protection is a feature in spreadsheet software that allows you to lock certain cells to prevent them from being edited. By default, when you protect a worksheet, all cells are locked. However, if you want some cells to be editable, you must first unprotect these cells before applying the worksheet protection. This way, while most of the worksheet remains locked and cannot be modified without unprotecting the sheet with a password, the unprotected cells are freely editable by any user.
For example, if you have a spreadsheet where you expect other users to only enter data into a set of input cells and not touch the rest of the document, you would unprotect the input cells and leave the remainder of the worksheet locked. This ensures data integrity for the rest of the document while providing flexibility where it's needed.
