## ISODD Function in Excel: 4 Suitable Examples

Now, I will talk about the examples one by one.

### Example 1: Find Odd Numbers Using ISODD Function

First of all, I will show you how to find odd numbers using the **ISODD** Function.

**Steps:**

- First of all, go to
**E5**and write down the following formula

`=ISODD(B5)`

- Then, press
**ENTER**to get the output.

** **

- After that, use the
**Fill Handle**to**AutoFill**up to**E12**.

### Example 2: Highlight Odd Rows Using ISODD Function

Now, I will show another example highlighting odd numbers using **the ISODD function**.

**Steps:**

- First of all, select the dataset.
- Then, go to the
**Home** - After that, select
**Conditional Formatting**. - Finally, select
**New Rule**.

- A box will appear. Write down the formula in the
**Rule Description.**

`=ISODD(ROW(B4:D12))`

- After that, select
**Format**.

- Then, click
**OK**.

**New Formatting Rule** - After that, write down the following formula

`=ISODD(D5)`

- Then, click

**Excel**will highlight the odd numbers.

### Example 4: Find Even and Odd Numbers Combining IF and ISODD Functions

The last example I am going to show is how you can find even and odd numbers using a combination of the **IF** and **ISODD** functions. For this example, I will use the dataset of the previous example. I have calculated the summation of all the marks and will determine which ones out of these marks are even or odd.

**Steps:**

- Go to
**I5**and write down the following formula

`=IF(ISODD(H5),"Odd","Even")`

- Then, press
