The OR function is one of Excel’s Logical functions. Like other logical functions, the OR function gives only a TRUE or FALSE answer.
To determine whether the output will be TRUE or FALSE, the OR function evaluates at least one mathematical expression located in another cell in the spreadsheet.
The syntax for the OR function is:
= OR ( logical-1 , logical-2 , ... logical-255 )
logical - refers to the cell reference that is being checked. Up to 255 logical values can be entered into the function.
