Logical Functions in Excel

Logical functions allow you to determine whether a value is true or false depending on the contents of the selected cells. Specified criteria are set in the calculation to find out whether certain conditions are met or not. Logical functions are useful calculations that can be made to find out if certain criteria are met among a range of selected cells.
