How to Protect a Worksheet in Excel 2010


Occasionally you will create a worksheet in Excel 2010 that contains data that you need to share, but that you don’t want someone to be able to edit. An effective way to handle this situation is to protect that worksheet with a password. This will configure the spreadsheet so that it can be opened and viewed, but the file viewer will not be able to edit any of the information without having the password that you set when you protected the sheet.
