This is where Worksheet_Calculate comes into play. In this article, we will explore the various ways of using Worksheet_Calculate in Excel.

What is Worksheet_Calculate?

Worksheet_Calculate is an event that occurs when the Excel worksheet is calculated. It allows us to automate tasks that need to be performed when a cell's value changes, or a formula is updated. In essence, it helps us to save time by automating repetitive tasks.

How to Use Worksheet_Calculate

To use Worksheet_Calculate, we need to create a VBA macro. Here is a step-by-step guide to creating a simple macro that will execute when a cell's value changes:

Step 1: Open the Visual Basic Editor

To open the Visual Basic Editor, press "Alt + F11" on your keyboard.

Step 2: Create a New Macro

In the Visual Basic Editor, click "Insert" and then "Module". This will create a new module where we can write our macro.

Step 3: Write the Macro

In the new module, write the following code:

Private Sub Worksheet_Change(ByVal Target As Range)

End Sub

This code creates a subroutine called "Worksheet_Change", which will be executed whenever a cell's value changes.
