 # How to Apply Logical Functions in Excel?

In Excel, logical functions are among the most popular and helpful. They can use the results of the test to evaluate data in other cells and take actions based on the results. This allows us to automate spreadsheet tasks. AND, OR, XOR, and NOT are the Logical functions. When you wish to do many comparisons in your calculation or test several conditions rather than one, you utilize these functions. When their parameters are evaluated, Excel logical functions return TRUE or FALSE, much like logical operators.

Facts and Figures of Excel’s Logical Functions

• Comparison operators, cell references, Boolean values, numeric and text values, and other Excel operations can all be used as parameters for logical functions. All parameters, however, must evaluate to TRUE or FALSE Boolean values, or pointers or arrays holding logical values.
• If a logical function’s argument has any empty cells, their values are disregarded. The formula produces a #VALUE! error if all of the parameters are empty cells.
• If none of the parameters evaluate logical values, a logical function gives the #VALUE! error.
• You can use up to 255 parameters in a logical function as long as the entire length of the formula doesn’t quite exceed 8,192 characters. You can use up to 30 variables in Excel 2003 and earlier, and the overall length of your formula must not surpass 1,024 characters.
• If a logical function’s input comprises numbers, the value of zero is FALSE, but all other values, even negative ones, are TRUE. If the A1:A5 cell comprises numbers, for instance, the formula =AND (A1:A5) returns TRUE if neither of the cells contains 0, and FALSE otherwise.

Using Excel’s AND Function

The AND function is by far the most widely used logic function in the world. It’s useful when you need to test many conditions and make sure they’re all satisfied. The AND function, in technical terms, evaluates the criteria you give and returns TRUE if all of them equate to TRUE, FALSE otherwise. Refer to an excel video for more clearance.

Using Excel’s OR Function

Excel’s OR function, like AND, is a fundamental logical function for comparing two numbers or expressions. The OR function yields TRUE if minimum one of the inputs evaluates to TRUE, and FALSE if all of the arguments evaluate to FALSE. In all versions of Excel, the OR function is accessible.

Using Excel’s NOT function

The NOT function in Excel is used to reverse the value of an input. In other words, the NOT function will return TRUE if logical equates to FALSE, and vice versa.
