How VBA runs javascript code

VBA (Visual Basic for Applications) is a macro language based on the Microsoft Visual Basic programming language for writing and automating tasks and operations in Microsoft Office applications. VBA can be used for many tasks, including automating documentation, generating reports, and manipulating data. Although VBA is a powerful tool, in some cases it may not provide the functionality you need. At this time, the required functionality can be achieved by running JavaScript code.

In this article, we will introduce you how to use VBA to run JavaScript code.

Step One: Create a VBA Program

First, you need to create a new VBA program in your Microsoft Office application. This can be achieved by selecting the "Visual Basic" button in the "Developer" tab. This opens the Visual Basic for Applications editor.

Step 2: Add a new module

In the Visual Basic Editor, select the "Module" option in the "Insert" menu. This will create a new code module where you can write VBA and JavaScript code.

Step 3: Copy the JavaScript code into the VBA code module

Now, you need to add the JavaScript code in the VBA code module. To achieve this you need to use the "CreateObject" function and the "Run" method. Here is the sample code:

Sub RunJavaScript()
  Dim js As Object
  Set js = CreateObject("ScriptControl")
  js.Language = "JScript"
  js.AddCode "function GetMessage() { return 'Hello, World!';}"
  MsgBox js.Run("GetMessage")
End Sub

Let’s take a look at the above code.

First, we create an object named "js". We then instantiate the JavaScript interpreter (ScriptControl) into a "js" object using the "CreateObject" function. Next, we specify the programming language to use by setting the "Language" property to "JScript". We then add the JavaScript code to the object using the "AddCode" method. Finally, we use the "Run" method to run the JavaScript code and display the message in the popup window.

Step 4: Execute the Code

Now you have added the JavaScript code to your VBA program. To run the code, press "F5" or click the "Run Subroutine" option in the "Run" menu.

Summary

Using VBA to run JavaScript code is a useful way to extend functionality in Microsoft Office applications. In this process, a VBA program is created, JavaScript code is copied into it, and the code is executed through the "CreateObject" function and the "Run" method. Using this approach, you can easily extend the functionality of your Microsoft Office applications and enable them to perform the desired actions.
