## Symbols

Just like other applications in Microsoft’s Office suite, Excel too has the Symbol feature where you can use a dialog which lists all supported characters in one place. You can find the **Symbol** dialog by following the **INSERT > Symbols > Symbol** path in the Ribbon.

In the **Symbol** dialog, choose **Mathematical Operators** from the **Subset** dropdown, and scroll down to find the *square root* character. Select the *square root* and click the **Insert** button.

Alternatively, you can use the character code. First, select **Unicode (hex)** in the **from** dropdown, and then type **221A** (with a capital “A”) into the **Character code** box.

## Symbol Font

The square root symbol is available in the font group named **Symbol**. All you need to do change a cell font to **Symbol** and enter “Ö”. The “Ö” character should be uppercase as shown below. Note that this method may not be available if you don’t have this character on your keyboard.

## Formula

You can also insert this symbol using a formula. The **UNICHAR** function of Excel can return a Unicode character based on the numeric value provided. All you need to do is enter the number 8730 into the function to get the square root symbol.

## Alt Code

You can insert a square root symbol in Excel using only your keyboard, without any additional steps. All you need to do is to hold down the **Alt** button and then type in the corresponding code for this character. In this case, while holding down the **Alt** key, press **251** to add a square root.

The difference between this and *symbol font* approaches is that you do not need to change font when using the *Alt* method.
