Unhiding columns in Microsoft Excel is the process of making hidden columns visible again. Columns can be hidden for various reasons, such as to declutter a worksheet, protect sensitive data, or improve performance. Whatever the reason, unhiding columns is a simple process that can be done in a few steps.
There are two main ways to unhide columns in Excel. The first is to use the “Unhide” command on the Home tab. To do this, select the column to the left of the hidden column, then click on the “Unhide” button in the Cells group. The hidden column will then be unhidden.
