What is VBA
• Full Form:
• Visual Basic for Applications
• VBA is Microsoft's common application programming
(macro) language for:
Many more
What does VBA do?
• Write Macros to Automate
• When to start automating
Labor-Intensive (Lot of manual efforts)
Repetitive or Routine Tasks
The Developer tab, which does
not appear by default, contains
useful commands for VBA users
About Macro Security
• Macros are so powerful that they can do serious damage to your
• Was created to help prevent macro-related problems
About Macro Security
• With this setting if you open the workbook, excel displays a security
warning above the formula bar
• Click enable content and the macros will be enabled
About Macro Security
If the Visual Basic Editor window is open when you open a
workbook that contains macros,
Excel does not display the Security Warning above the Formula
bar. Rather, it displays a dialog box with two buttons:
Enable Macros and Disable Macros
Saving Workbooks That
Contain Macros
Extension of Visual Basic:
Excel warns you if your workbook contains macros and you attempt to save it
in a nonmacro file format
Types of VBA Macros
Nickname of Macro: Procedure
Two Types of Macro: Sub and Function
A Sub procedure is a series of Visual Basic statements enclosed by
the Sub and End Sub statements
Go to excel - It will help in opening the window wherein you can write the
macro code
Alt + F11
Go to excel  To run the macro at one go

Creating VBA Macros
 Concepts – Objects
 Such as Worksheet, Workbook, Range, Cell, Chart,
Name, etc.
 Worksheets(1) is an Object Referring to the First Sheet
 Range("A1:B15") is an Object Referring to a Range
 Cells(1,1) or Range(“A1”) is an Object Referring to
Range “A1”
Workbook Objects
Workbook Objects
The Workbook object is a member of the Workbooks collection and
contains all the Workbook objects currently open in Microsoft Excel
'Ex 1 : To close Workbooks
'Ex 2 : To Add an Empty Work Book
'Ex 3: To Open a Workbook
Workbooks.Open FileName:="Test.xls", ReadOnly:=True
'Ex : 4 - To Activate WorkBooks
Writing the data to first Cell of
the Worksheet
Workbook Objects
The Workbook object is a member of the Workbooks collection and
contains all the Workbook objects currently open in Microsoft Excel
Sub US()
Cells(1, 1)="Hello World"
End Sub
‘Here the first value (1) is Row Value and the second one (1) is
column value
‘Cells(1, 1) means first row first column
Writing the data from first Cell
of the worksheet
Workbook Objects
The Workbook object is a member of the Workbooks collection and
contains all the Workbook objects currently open in Microsoft Excel
Sub US()
Range(“A2”)="Hello World"
End Sub
(‘Here you have to specify the Cell Name which you want to
read – A is the Column and 2 is the Row)
Worksheet Objects
Worksheet Objects
The Worksheet object is a member of the Worksheets collection and
contains all the Worksheet objects in a workbook
'Ex 1 : To make it Invisible
Worksheets(1).Visible = False
'Ex 2 : To protect an WorkSheet
Worksheets("Sheet1").Protect password:=strPassword,
Sub gaurav()
Cells(2, 3).Select
Selection.Font.Bold = True
Selection.Font.Italic = True
End Sub
Range Objects
Range Objects
Range Objects represent a cell, a row, a column, or a selection of
cells containing one or more continuous blocks of cells
'Ex 1 : To Put a value in the cell A5
Worksheets("Sheet1").Range("A5").Value = "5235"
'Ex 2 : To put a value in range of Cells
Worksheets("Sheet1").Range("A1:A4").Value = 5
Final Example
Sub juhi()
Cells(2, 3) = "Hello life"
Range("A1") = "Hello life"
Cells(2, 3).Select
Selection.Font.Bold = True
Cells(2, 3).Select
Selection.Font.Italic = True
End Sub
Displaying the Developer tab
1. Choose Office ➪ Excel Options.
2. In the Excel Options dialog box, select Personalize.
3. Place a check mark next to Show Developer tab in the Ribbon.
4. Click OK to return to Excel.
Difference Between Cell and Range
Cells usually reference a single cell at a time.
Cells(Parameter1, Parameter2)
Eg: Cells (Row no., Column no.)
Cells (2,3)
Cells (3,4)
Range can refer a group of cells at once: Range(“Column row
More Examples with Range
Sub juhi()
Range("A1") = "Hello life"
Selection.Font.Bold = True
Selection.Font.Italic = True
End Sub
Example of Basic Logical Operator
Sub juhi()
Range("A7").Formula = "=Sum(D17:E17)"
Range("A4").Formula = "=D17-E17"
Range("A1").Formula = "=average(A4:B7)"
Range("A10").Formula = "=A5*A7"
End Sub
Example to get the current date and time
Sub TimeStamp()
‘ TimeStamp Macro
‘ Keyboard Shortcut: Ctrl+Shift+T
ActiveCell.FormulaR1C1 = “=NOW()”
Or Activecell.formula = “=NOW()”
Selection.PasteSpecial Paste:=xlPasteValues, _
Operation:= xlNone, SkipBlanks _
:=False, Transpose:=False
Application.CutCopyMode = False
End Sub
Sub juhi()
ActiveCell.FormulaR1C1 = "=NOW()"
Application.CutCopyMode = False
End Sub
The procedure has four statements.
First statement inserts NOW() formula into the active cell.
Second statement copies the cell.
Third statement, which is displayed on three lines (the underscore
character means that the statement continues on the next line), pastes
the Clipboard contents (as a value) to the current selection.
The fourth statement cancels the moving border around the selected
Note: You may notice that the macro recorded some actions that you
didn’t take. For example, it specified several options for the
PasteSpecial operation. Recording actions that you don’t specifically
make is just a byproduct of the method that Excel uses to translate
actions into code.
For Loop
For NEXT Loops
You can use a For-Next loop to execute one or more
statements a number of times.
For-Next loop:
Sub SumSquared()
Total = 0
For Num = 1 To 10
Total = Total + (Num ^ 2)
Next Num
MsgBox Total
End Sub
This example has one statement between the For
statement and the Next statement. This single
is executed 10 times. The variable Num takes on
successive values of 1, 2, 3, and so on, up to 10.
The variable
Total stores the sum of Num squared, added to the
previous value of Total. The result is a value that
represents the sum of the first 10 integers squared.
This result is displayed in a message box.
Sub SumSquared()
Total = 0
For Num = 1 To 10
Total = Total + Num
Next Num
MsgBox Total
End Sub
Single Loop with Cells
You can use a single loop to loop through a one-dimensional
range of cells
Sub juhi()
For A = 1 To 6
Cells(A, 1).Value = 100
Next A
End Sub
Double Loop
You can use a double loop to loop through a two-dimensional range of cells.
Sub juhi()
For i = 1 To 6
For j = 1 To 2
Cells(i, j).Value = 100
Next j
Next i
End Sub
Do While Loop
A Do…While loop is used when we want to repeat a set of
statements as long as the condition is true.
Sub juhi()
i = 1
Do While i < 6
Cells(i, 1).Value = 20
i = i + 1
End Sub
Example of Msgbox
The MsgBox is a dialog box in Excel VBA you can use to inform the
users of your program.
1. A simple message.
MsgBox "This is fun"
Result when you click the command button on the sheet:
More Examples
A little more advanced message. First, enter a number into cell A1.
MsgBox "Entered value is " & Range("A1").Value
Result when you click the command button on the sheet:
Recording VBA macros
Excel’s macro recorder translates your actions into VBA code. To start the
macro recorder, choose Developer ➪ Record Macro
To begin recording your actions, click
OK. When you finish recording the
macro, choose Developer ➪
Code ➪ Stop Recording (or click the
Stop Recording button in the status
The MyName procedure was generated by Excel’s macro recorder
The macro recorded is a Sub procedure that is named MyName. The
statements tell Excel what to do when the macro is executed
ActiveCell.FormulaR1C1 = “John Walkenbach”: Statement causes the
name to be inserted into the active cell. The FormulaR1C1 part is a
Example of a code
When this code is executed, VBA inserts the following:
• Current date into the active cell
• Formats it
• Makes the cell bold
• Adjusts the column width
