Conditional Formatting is automatically updated if you change data in the worksheet
Step-by-step explanation:
Conditional formatting is useful to present data, add certain color codes to understand data quickly. There are different kinds of conditional formatting such as highlight cells that are greater than the given value, highlight cells that are above average, clear formatting for selected cells etc.
