# Excel OR Function

The OR function is a logical function to test multiple conditions at the same time. OR returns either TRUE or FALSE. For example, to test A1 for either "x" or "y", use =OR(A1="x",A1="y"). The OR function can be used as the logical test inside the IF function to avoid extra nested IFs, and can be combined with the AND function.

**logical1**- The first condition or logical value to evaluate.**logical2**- [optional] The second condition or logical value to evaluate.

Use the OR function to test multiple conditions at the same time, up to 255 conditions total.

For example, to test if the value in A1 OR the value in B1 is greater than 75, use the following formula:

=OR(A1>75,B1>75)

OR can be used to extend the functionality of functions like IF. Using the above example, you can supply OR as the logical_test for an IF function like so:

This formula will return "Pass" if the value in A1 is greater than 75 OR the value in B1 is greater than 75.

### Array form

If you enter OR as an array formula, you can test all values in a range against a condition. For example, this array formula will return TRUE if any cell in A1:A100 is greater than 15:

={OR(A1:A100>15}

Notes:

- Each logical condition must evaluate to TRUE or FALSE, or be arrays or references that contain logical values.
- Text values or empty cells supplied as arguments are ignored.
- The OR function will return #VALUE if no logical values are found

## Excel Formula Training

Formulas are the key to getting work done in Excel. In this accelerated video course, you'll learn how to use formulas to manipulate text, work with dates and times, lookup values with VLOOKUP and INDEX & MATCH, count and sum with criteria, dynamically rank values, and create dynamic ranges. You'll also learn powerful skills to troubleshoot, trace errors, and fix problems. This is the formula training you should have had to begin with. See details here.
