Explain macros. What benefit does employing a macro have?

A collection of instructions (also known as code) kept in a VBA editor’s Visual Basic module is called a VBA macro. A module contains the code for the VBA macros. Go to the VBA editor and select Insert -> Module to add a module.

Excel users can automate routine repetitive operations on a daily or weekly basis by executing VBA macros. Thus, you may increase productivity, save time, and meet client deadlines by utilizing macros.

What is meant by “option explicit” in your understanding?

When utilizing VBA, the explicit option is utilized to mandate that variables be declared before usage. It aids in avoiding type mistakes and producing bug-free code for VBA developers.

Which kinds of fundamental modules are available in the Visual Basic Editor?

VBE’s three distinct modules are offered:

Class Module: Default modules that are frequently used for function writing.

UserForms: They support the development and design of GUI programs.

Class modules facilitate the creation of new items, ethos, processes, and events by the user.

Describe the process of passing arguments to VBA functions.

Two methods exist in VBA Subroutines and Functions for passing arguments:

ByVal: The value assigned to an argument is supplied to the procedure when an argument is passed by value. Furthermore, any modifications made to the argument throughout the procedure will be lost after it concludes.

ByRef: The actual address associated with the argument is supplied to the procedure when an argument is passed by reference. After the procedure, any modifications made to the argument will be approved.

And in VBA, ByRef is the default.

How can you set up Excel VBA macros to run automatically when I open a workbook?

One of the most often requested questions and answers during Excel VBA interviews is this one. When a workbook is opened in Excel VBA, you may utilize the Workbook_Open() Event to have macros run automatically.

Please follow these procedures to obtain the Workbook_Open() Event in Excel.

  1. Access the VBA Editor.
  2. From the Project Explorer, select “ThisWorkbook.”
  3. Two drop-down lists are now visible on the right side.
  4. From the first drop-down menu, select “Workbook,” and from the second drop-down menu, select “Open.”
  5. The code that follows is now visible.

Private Sub Workbook_Open()

     ‘Your Statements…..

End Sub

  1. To execute a macro, insert the code in between the lines above.
  2. Close and save the worksheet.
  3. To test the macro, reopen the workbook.

Private Sub Workbook_Open()

    MsgBox “Workbook has Opened Successfully.”, vbInformation

End Sub

In the example above, the macro will launch automatically as soon as the worksheet is opened. A notification similar to “Workbook has Opened Successfully” will now appear.

Alternatively, we may construct a code module procedure called Auto_Open() that will run when the macro file is opened.

An object variable can be created and used throughout the process. Please refer to the examples below to build an object for a worksheet, workbook, etc.

Make an object for the workbook:

Sub Create_Object_Workbook()

    Dim Wb As Workbook

    Set Wb = ActiveWorkbook

    MsgBox Wb.Sheets(1).Name

End Sub

Explanation: We generated and assigned the “Wb” object to the Active Workbook in the example above. We then used it to display the name of the first worksheet in the following statement (MsgBox Wb.Sheets(1).Name).

Describe an array

A collection of variables with similar types is called an array. By using the array name and the index number (also known as the subscript), you can use an array to refer to a specific value.

The following is how we may declare and build an array variable for size.

Dim ArrayName As Datatype (IndexNumber)

Example: Dim aValue(2) As Integer

The array name “aValue” and the array size “2” are indicated in the above statement.

Define Data Type

Data Type: A data type indicates the sort of variable that will be used in a function or process. A data type is a set of specifications that indicate how much space a variable requires.

Since different variables take up varying amounts of memory space, we must determine how much space a variable will take up before using it.

The variable can be declared in the manner shown below.

Dim VariableName as Datatype


Dim iCnt as Integer

where Integer denotes datatype and iCnt stands for variable name.
