The Excel NOT function is a logical function that helps you evaluate and negate the value of a given expression. It returns TRUE if the expression is FALSE, and FALSE if the expression is TRUE. In simpler terms, it flips the logical value of a statement. This can be quite useful when you need to check for the opposite condition of a specific logical test.

## Syntax

**NOT(logical)**

## Arguments

logical | The value or expression you want to negate. It should be either TRUE or FALSE or any formula or comparison that results in a logical value. |

## How to use

The Excel NOT function is straightforward to use. You simply need to provide a logical value or expression as an argument. Here are some examples to illustrate its use:

1 |
=NOT(TRUE) |

This formula will return **FALSE** because it negates the logical value **TRUE**.

1 |
=NOT(FALSE) |

Conversely, this formula will return **TRUE** because it negates the logical value **FALSE**.

1 |
=NOT(5>10) |

Here, the formula checks if 5 is greater than 10, which is **FALSE</b. Applying NOT to it will return TRUE.**

1 |
=NOT(A2="Apple") |

If cell A2 contains the text “Apple,” this formula will evaluate to **FALSE</b. However, applying NOT will change it to TRUE.**

Excel NOT function can be especially handy when used in combination with other logical functions or as part of more complex formulas to manipulate and analyze data effectively.
