The Excel OR Function

Related Function:
AND Function

Basic Description

The Excel OR function tests a number of supplied conditions and returns either:

- TRUE if ANY of the conditions evaluate to TRUE
- FALSE otherwise (i.e. if ALL of the conditions evaluate to FALSE)

The syntax of the function is :

OR( logical_test1, [logical_test2], ... )

where the logical_test arguments are one or more conditions that evaluate to either TRUE or FALSE.

You can enter up to 255 conditions to the Excel Or function in Excel 2007 or 2010. However, in Excel 2003, the function can only handle up to 30 arguments.

Note that, if the logical_tests return numbers, instead of logical values, zero is treated as the logical value FALSE all non-zero numbers are treated as the logical value TRUE.
