Excel file protection
In these links you will find information about the possibilities that are available in Excel.
Lock or unlock specific areas of a protected worksheet
By default, protecting a worksheet locks all cells so none of them are editable. To enable some cell editing, while leaving other cells locked, it's possible to unlock all the cells. You can lock only specific cells and ranges before you protect the worksheet and, optionally, enable specific users to edit only in specific ranges of a protected sheet.
To prevent other users from accidentally or deliberately changing, moving, or deleting data in a worksheet, you can lock the cells on your Excel worksheet and then protect the sheet with a password. Say you own the team status report worksheet, where you want team members to add data in specific cells only and not be able to modify anything else. With worksheet protection, you can make only certain parts of the sheet editable and users will not be able to modify data in any other region in the sheet.
To prevent other users from viewing hidden worksheets, adding, moving, deleting, or hiding worksheets, and renaming worksheets, you can protect the structure of your Excel workbook with a password.
