# Excel ISODD Function

We can use the Excel ISODD function to test whether an imputed numerical value is an odd number. This article will walk through the simple steps.

Figure 1 – How to Use the Excel ISODD function

## General Formula

`=ISODD(value)`

• “Value” is the numerical value we want to test if it is ODD

## Formula

`=ISODD(B5)`

## Setting up the Data

We will structure our table in the pattern as shown in figure 2. We want to check if each number under the “value” column is an odd number.

• We will input the values in the range B5:B10
• The RESULTS will be displayed in Column C

The ISODD function checks if the specified value or cell reference has an ODD number and returns the result with a TRUE or FALSE. If there is no numeric value in the cell, then the ISODD function will return the #VALUE error.
