Sometimes you want to scroll a large worksheet by keeping one or more Columns of a worksheet visible while you scroll columns. For example, you may want to see the first Column of the worksheet while you scroll horizontally to right-side within Excel worksheet. There is a feature in Excel called Freeze Panes to keep some Columns always visible while you scroll horizontally.
To Freeze Pane vertically at a Column, follow below steps.
Step 1 - Select the right-side Column of the Column which you want to freeze by clicking on its Column Letter, as shown below. In this example, I want to freeze at Column A (left-most column). So I had selected Column B, by clicking on its Column Letter.
Step 2 - Click "Freeze Panes" menu and then select "Freeze Panes" from Excel Ribbon > "View" Tab > "Window" Group as shown below.
Step 3 - As you can see from below image, Column A is frozen and it is always visible as you scroll to right-side within Excel worksheet.
