How To Make A Vba Function In Excel

Creating a VBA Function in Excel

VBA (Visual Basic for Applications) is a programming language that allows you to create custom functions in Excel. These functions can perform calculations, manipulate data, and automate tasks in your Excel spreadsheets.

To create a VBA function in Excel, follow these steps:

1. Open Excel and press Alt + F11 to open the Visual Basic Editor.
2. In the Visual Basic Editor, click on Insert and then choose Module to insert a new module.
3. In the module, you can start writing your VBA function. Here is an example of a simple function that adds two numbers:

        Public Function AddNumbers(a As Integer, b As Integer) As Integer
            AddNumbers = a + b
        End Function
    

The above function is named AddNumbers and takes two parameters a and b as input. It returns the sum of a and b.

Once you have written your function, you can use it in your Excel worksheet just like any other built-in Excel function. Here’s how:

1. Switch back to your Excel worksheet.
2. In a cell where you want to display the result of the function, type =AddNumbers(3, 5) (assuming you want to add the numbers 3 and 5).
3. Press Enter or Return to get the result.

The cell will now display the result of the AddNumbers function, which is 8 in this case.

You can also use the VBA function in other formulas, combine it with other Excel functions, or assign it to a button or a macro for further automation.

Remember to save your Excel workbook as a macro-enabled (.xlsm) file if it contains VBA code.
