• Enter the number 1 in the first cell.
• In the next cell, enter the formula =A1+1 (assuming A1 is the first cell).
• Drag the fill handle down to auto-fill the running numbers in subsequent cells.

Step 3: New Line in a Cell

To add a new line within a single cell:

Step 4: Fix Header Row

Keeping your header row visible while scrolling through your data can be helpful.

• Click on the row number just below your header row.
• Go to the View tab and click on "Freeze Panes."
