# How to Insert Function (Dialog Box) in Excel & Google Sheets

*This tutorial demonstrates how to insert a function through the dialog box in Excel and Google Sheets.*

## Insert Function via Dialog Box

To insert a function in Excel, you can type it directly into the formula bar, or use the dialog box to insert a function. Say you want to insert the **SUM Function**.

- Click the
**Insert function icon**next to the formula bar.

- In the Insert Function window, you can search for the function you need.
**Type the function**into the**search box**(*SUM*) and click**Go**. As you can see in the picture below, you get all functions containing the searched term. Choose the function you want from the list and click**OK**.

- Now you get the Function Arguments window, where you can
**enter all arguments**, and see their detailed explanation. Click**OK**to confirm.

**Note**: In the Insert Function dialog box, you can also choose a function from a certain category. In the drop down, choose the category you need, and you get a list of all functions from that category. By default, the most recently used functions are displayed.

## Insert Function in Google Sheets

In Google Sheets, the dialog box for inserting function is not available. However, you can see the detailed explanation for function arguments. **Type the function** in the formula bar (**=SUM(**), and **click the down arrow**.

As a result, you can see the explanation and example of the function, as well as arguments details.

**Shortcuts**

**SHIFT + F3**. - Open the Insert Function dialog box from within a cell with
**CTRL + A**. - Insert function arguments into a cell with
**CTRL + SHIFT + A**. - Toggle Formula View mode on and off with
