Explanation: Firstly, recall that NOT function returns the opposite to a supplied logical value
Cell A3 in the example above uses Excel Isblank function with the Not function, to test if cell B1 is blank.
The syntax for the NOT function in Microsoft Excel is:
NOT( logical_value )
- An expression that either evaluates to TRUE or FALSE. If used with an expression of TRUE, then FALSE is returned. If used with an expression of FALSE, then TRUE is returned.
If the logical_value is TRUE, then the NOT function will return FALSE.
If the logical_value is FALSE, then the NOT function will return TRUE.
Note that, if the supplied logical argument is a numeric value, zero is treated as the logical value FALSE and any other numeric value is treated as the logical value TRUE.
