AND Function - Microsoft Support

The AND function returns TRUE if all its arguments evaluate to TRUE, and returns FALSE if one or more arguments evaluate to FALSE.

One common use for the AND function is to expand the usefulness of other functions that perform logical tests. For example, the IF function performs a logical test and then returns one value if the test evaluates to TRUE and another value if the test evaluates to FALSE. By using the AND function as the logical_test argument of the IF function, you can test many different conditions instead of just one.

Syntax

AND(logical1, [logical2], ...)

The AND function syntax has the following arguments:

Argument

Description

Logical1

Required. The first condition that you want to test that can evaluate to either TRUE or FALSE.

Logical2, ...

Optional. Additional conditions that you want to test that can evaluate to either TRUE or FALSE, up to a maximum of 255 conditions.

Remarks

  • The arguments must evaluate to logical values, such as TRUE or FALSE, or the arguments must be arrays or references that contain logical values.

  • If an array or reference argument contains text or empty cells, those values are ignored.

  • If the specified range contains no logical values, the AND function returns the #VALUE! error.
