Locking cells in a spreadsheet

Excel 365 2016 2013 2010 2003
Sometimes you might want to lock cells in your Excel spreadsheet that contain formulas and functions or data. Thus, the person doing the data entry will not accidentally overwrite or delete the spreadsheet formulas and functions or your data.

Locking cells in an Excel spreadsheet is a two-step process. By default all cells are locked. You must first select and unlock the cells. Then, you must turn on protection on the entire spreadsheet for the "lock" to go into effect.

Follow these steps to unlock cells on a spreadsheet:

   1.   Select the cells in the spreadsheet that you want to unlock.

   2.   On the Home tab, in the Cells group, click Format, and then click Format Cells:

   3.   On the Protection tab, clear the Locked check box, and then click OK.

   4.   Now you must protect the entire spreadsheet to have the lock feature protect the cells. On the Review tab, in the Change group, click Protect Sheet:

   5.   Enter a password if you want to require a password for "unprotecting" the spreadsheet.
