Learn how to use the XLOOKUP function with Boolean expression (OR logic). To do that, set the lookup value to 1.

**XLOOKUP is our favorite dynamic array function**, which you can use in various situations.

## Generic formula to use a boolean or logic

In the example, our goal is to find and list all records where the color is “orange” or “blue”.

**Formula:**

**=XLOOKUP(1 ,boolean_expression, data)**

The **arguments** of the XLOOKUP function:

- lookup value is
**1**; in other words, TRUE. - lookup_array is
**an expression**, and it has two possible outputs (TRUE or FALSE) based on the boolean logic - the lookup array is named range,
**“sales_table”**, (B3:D10)

**Note:** sales_data is a **named range** and is referred to as range B3:D10.

**Formula:**

**=XLOOKUP(1, (C3:C10=”blue”)+(C3:C10=”orange”), sales_data)**

Good to know when you use boolean logic; Excel follows the rules below:

**Multiplication (*)**corresponds to the**AND operator****Addition (+)**corresponds to**OR operator**

### XLOOKUP with Boolean OR logic

Working from the inside out, we will evaluate the following expressions:

=C3:C10 = “blue”

=C3:C10 = “orange”

Take a look at the first array in column F. If the color is “blue” in the given row in range C3:C10, the expression returns with TRUE (1), else FALSE (0).

The =C3:C10 = “orange” expression gets TRUE (1) if the cell value is “orange”, else gets FALSE (0).

We will apply math operators to convert the TRUE and FALSE outputs to 1 or 0. But, first, create a helper column. Use the “+” sign to create the lookup_array for the second argument of XLOOKUP.

**Evaluate the =(C3:C10=”blue”)+(C3:C10=”orange”) section**:

The result is 1 if the cell contains the “blue” OR “orange” value. Now have the lookup array for the second argument of XLOOKUP.

The formula looks like this:

**=XLOOKUP(1, {0,0,0,1,1,1,0,1}, sales_data)**

Evaluate the formula:

The formula will find the first matching record that meets the boolean or logic criteria. In this case, the first matching record is in row 4.

## Workaround with the FILTER function

If you want to get **all matching records**, use the **FILTER** function.

**Formula:**

=FILTER(sales_table, (C3:C10=”blue”)+(C3:C10=”orange”))

**Result:**
