How To Create A Function In Excel Vba

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

1. Open Excel and press ALT + F11 to open the Visual Basic for Applications (VBA) editor.
2. In the VBA editor, go to Insert at the top menu and click on Module to insert a new module.
3. In the module, define your function using the following syntax:

   
                   Function functionName(argument1 As dataType, argument2 As dataType, ...) As returnType
                       ' Your code goes here
                   End Function
               

4. Replace functionName with the desired name of your function. Specify the arguments in parentheses, separated by commas, and use the As dataType to specify the data type of each argument. Use As returnType to specify the data type of the value the function will return.
5. Write your desired code within the function. You can use variables, loops, conditional statements, and any other Excel VBA functionality.
6. At the end of the function, use the FunctionName = returnValue statement to assign the value you want the function to return. Replace returnValue with the desired value or a variable that holds the value.
7. Save your VBA project and close the VBA editor.

Here’s an example of a simple function that adds two numbers in Excel VBA:

        Function AddNumbers(num1 As Double, num2 As Double) As Double
            AddNumbers = num1 + num2
        End Function
    

This function takes two arguments of Double data type and returns their sum as a Double.

You can use the function in your Excel worksheet by typing “=AddNumbers(5, 7)” in a cell, which will return the result “12”.
