How to Unlock Cells in Excel 2016


Excel 2016 allows you to lock and unlock cells to prevent accidental changes to important data. Here's a step-by-step guide on how to unlock cells in Excel 2016:

Accessing the protected worksheet


To unlock cells in Excel 2016, you first need to access the protected worksheet where the cells are located. Click on the Review tab on the ribbon, then select "Unprotect Sheet" from the Changes group. You may be prompted to enter a password if the worksheet is protected.
