VBA Interview Questions and Answers
Intermediate / 1 to 5 years experienced level questions & answers
Ques 1. Explain the difference between 'ByVal' and 'ByRef' in VBA.
'ByVal' passes the value of the variable to the function, while 'ByRef' passes a reference to the variable, allowing the function to modify its value.
Example:
Sub ModifyValue(ByRef x As Integer)
x = x + 1
End Sub
Ques 2. How do you handle errors in VBA?
You can use 'On Error' statements to handle errors. For example, 'On Error Resume Next' to ignore errors, or 'On Error Goto' to jump to a specified label.
Example:
On Error Resume Next
' code that may cause an error
On Error GoTo 0
Ques 3. Explain the purpose of the 'With' statement in VBA.
The 'With' statement allows you to perform a series of actions on a specified object without repeating the object reference. It enhances code readability and can improve performance.
Example:
With Range("A1")
.Value = 42
.Font.Bold = True
End With
Ques 4. Explain the difference between 'ActiveCell' and 'Selection' in VBA.
'ActiveCell' refers to the currently selected cell, while 'Selection' refers to the currently selected range of cells.
Example:
ActiveCell.Value = "Hello"
Selection.Font.Bold = True
Ques 5. How do you create a UserForm in VBA?
You can create a UserForm by right-clicking on the VBA project, selecting 'Insert' -> 'UserForm', and then design the form using the toolbox.
Example:
Sub ShowUserForm()
UserForm1.Show
End Sub
Ques 6. Explain the purpose of the 'Application' object in VBA.
The 'Application' object represents the entire Excel application and allows you to access and manipulate various application-level properties and methods.
Example:
Application.ScreenUpdating = False
Ques 7. What is the purpose of the 'ByVal Target As Range' parameter in a Worksheet_Change event?
The 'ByVal Target As Range' parameter represents the range of cells that triggered the change event. It allows you to perform actions based on the changed cells.
Example:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("A1:A10")) Is Nothing Then
' Code to execute when cells in A1:A10 are changed
End If
End Sub
Ques 8. Explain the difference between 'Worksheet' and 'Workbook' in VBA.
'Worksheet' refers to a single sheet within a workbook, while 'Workbook' represents the entire Excel file.
Example:
Dim ws As Worksheet
Set ws = ThisWorkbook.Worksheets("Sheet1")
Ques 9. What is the purpose of the 'Select Case' statement in VBA?
The 'Select Case' statement is used for multiple conditional tests, providing a cleaner alternative to nested 'If' statements.
Example:
Select Case x
Case 1
Debug.Print "Value is 1"
Case 2
Debug.Print "Value is 2"
Case Else
Debug.Print "Value is neither 1 nor 2"
End Select
Ques 10. What is the purpose of the 'Offset' property in VBA?
The 'Offset' property is used to refer to a cell or range of cells that is a specific number of rows and columns away from a given cell or range.
Example:
ActiveCell.Offset(1, 2).Value = "Data"
Ques 11. Explain the purpose of the 'Unload' statement in VBA.
The 'Unload' statement is used to remove a UserForm from memory.
Example:
Unload UserForm1
Ques 12. What is the purpose of the 'LBound' and 'UBound' functions in VBA?
'LBound' returns the lower bound of an array, and 'UBound' returns the upper bound of an array.
Example:
Dim myArray(1 To 10) As Integer
Debug.Print LBound(myArray) ' Outputs 1
Debug.Print UBound(myArray) ' Outputs 10
Ques 13. Explain the difference between 'Function' and 'Sub' in VBA.
'Function' is used to define a procedure that returns a value, while 'Sub' is used for procedures that do not return a value.
Example:

End Function
