Step 1. Selecting the Entire Worksheet
The initial step in locking a column in Excel is to select the entire worksheet.

To select the whole worksheet, click the small square where the column letters and row numbers intersect.

Step 2. Unlocking All Cells
In Excel, all cells are locked by default, but this lock only takes effect when the worksheet is protected. To unlock all cells, with your entire worksheet selected, head to the ‘Format Cells’ dialog box. This is located under the ‘Format’ dropdown menu in the ‘Home’ tab. Inside the dialog box, go to the ‘Protection’ tab and uncheck the ‘Locked’ option.
