cells
● Absolute Reference ($A$1): Remains constant whencopied
Visual: Show how formulas adjust when copied with relative
references vs. staying the same with absolute references.
Example: If you want to always refer to cell A1 in a formula, use
$A$1.

9. AutoFill and Flash Fill
● AutoFill: Quickly fill cells with a series (e.g., numbers, dates)

(e.g., Sheet2!A1).
● Organize your data logically across multiple sheets.

13. Data Validation
Ensure clean data entry:
● Dropdown Lists: Limit cell values to a predefined list.
● Error Alerts: Show a warning message if invalid data is
entered.
Example: Create a dropdown list for selecting department names to
prevent typos.

14. Named Ranges
● Assign names to cells or ranges (e.g., "SalesData").
