Lesson 3 : Writing Your Own VBA Code - 35 Examples

In the previous post, we have covered the following topics :

This tutorial gives you a plenty of hands-on examples to get you started with excel macros.

Let's understand a simple macro code.

Let’s take a simple example multiplying a cell by 2.

Sub Macro1()
Range("B2").FormulaR1C1 = "=RC[-1]*2"
End Sub
What is Sub?
To create a sub procedure, start with the Sub keyword.

What is Macro1?
It is a macro name. You can give your macro any name you want.

What is FormulaR1C1 ?
It is a formula reference style. The macro recorder always uses R1C1 reference style..

How does R1C1 differ from A1?
Instead of letters you get numbers. The numbers represent the relative distance from the current cell.

A1 - Columns followed by row number.
R1C1 - Rows followed by columns.

Let’s take a simple example multiplying two columns.

A1 Style

R1C1 Style

What does RC[-2] mean?
It refers to the cell 2 columns to the left of current cell.

Similarly, R[3]C[3] is a cell 3 rows down and 3 columns to the right. R[-2]C[-4] is a cell 2 rows up and 4 columns to the left.

Positive numbers - Cells below and/or across to the right.
Negative numbers - Cells above and/or to the left.

What is End Sub?
To end a sub procedure, use the End Sub keyword.

Where to write VBA code?

Module is an area where we write VBA code.

Instructions :
  1. Open Excel Workbook
  2. Press ALT + F11 to open visual basic editor (VBE)
  3. To insert a module, go to Insert > Module

To view a module, just double click on its icon in the Project Explorer window in the VBA Editor

35 Examples

The following is a list of hands-on examples to help you write your first macro.

1. Write value into a cell
  Task : Write 12 into cell B3
Sub Enteravalue()
Range("B3").Value = 12
End Sub

2. Add the same value into multiple ranges
Task : Enter 12 into cells B3 through B5 and C5 through C8
Sub Entervalues()
Range("B3:B5,C5:C8").Value = 12
End Sub

3. Select a cell
Task : Select cell B3
Sub macro1()
End Sub
4. Select a range
Task : Select range B3:B5
Sub macro2()
End Sub 
5. Select multiple ranges
Task : Select ranges B3:B5 and C5:C8
Sub macro3()
End Sub 
6. Copy/Paste
Task : Copy the data from range “B3:B5” and paste it into cells starting from G3
Sub copypaste()
End Sub
Another way to write the above program (copy and paste)
Sub copypaste()
Range("B3:B5").Copy _
End Sub
7. Copy/Paste Cell Value Only (Not Formula)
Task : Copy the data from range “B3:B5” and paste it into cells starting from G3
Sub copypaste()
Range("G3").PasteSpecial Paste:=xlPasteValues
End Sub
8. Copy the entire data from one sheet to another sheet
Task : Copy the entire data from “Sheet1” and paste it into “Sheet2”.
Sub entirecopy()
End Sub
9. Copy the entire row and paste it to another row
Task : Copy the fifth row from “Sheet1” and paste it to seventh row in the same sheet.
Sub entirerow()
End Sub
10. Clear contents only
Task : You want to clear only contents of the cells (not formats).
Sub clearcontent()
End Sub
11. Clear all formats and values
Task : You want to clear all formats and values from cells in addition to clearing the contents of the cells.
Sub clearall()
End Sub
12. Select the left most non-empty cell in a row
It moves the cursor to the left most non-blank cell in a row
Sub leftmost()
End Sub
13. Select the right most non-empty cell in a row
It moves the cursor to the right most non-blank cell in a row
Sub rightmost()
End Sub
14. Select the last non-empty cell in a column
It moves the cursor to the last non-blank cell in a column
Sub lastcell()
End Sub
15. Select the first non-empty cell in a column
It moves the cursor to the first non-blank cell in a column
Sub firstcell()
End Sub
16. VBA Message Box

The syntax for VBA message box is as follows :

Simple VBA Message Box
Sub Msg1()
MsgBox "Hello Everyone"
End Sub

17. Message Box With Title
Sub Msg2()
'Display message box with title "Introduction"
MsgBox "Hello Everyone",  , "Introduction"
End Sub

18. Advanced Message Box

Sub Msg3()
Dim Popup As Integer
Popup = MsgBox("Are you a lazy guy?", vbYesNo, "User's Attitude")
'If user clicks on Yes button then displays a message
If Popup = vbYes Then
MsgBox "Thank you for answering honsestly!!"
'If user clicks on No button then displays a message
MsgBox "Great!"
End If

In VBA message box, ‘buttons’ parameter can have any of the following values:

18. How to pass a value in message box
Sub Msg5()
MsgBox "Your final score is " & Range("A2").Value
End Sub

19. Find active cell positioning
Sub cellpos()
Rowf = ActiveCell.Row
Colf = ActiveCell.Column
MsgBox Rowf & "," & Colf
End Sub
 20. Conditional Statements - IF THEN ELSE
Sub Macro1()
If Range("A1") > 100 Then
Range("B1").Value = 1
ElseIf Range("A1") > 50 Then
Range("B1") = 0.5
Range("B1") = 0
End If
End Sub
21. SELECT CASE - Alternative to IF THEN ELSE
Sub Macro11()
Select Case Range("A1").Value
   Case Is > 100
    Range("B1").Value = 1
   Case Is > 50
   Range("B1").Value = 0.5
   Case Else
   Range("B1").Value = 0
   End Select
End Sub 
22. How to select a worksheet
Sub slctwrk()
'Select sheet2 worksheet
End Sub
 23. How to add new worksheet

End Sub
 25. How to delete a worksheet

Sub macro107()
End Sub

 32. Select current region without headers
Sub macro108()
Set tbl = ActiveCell.CurrentRegion
tbl.Offset(1, 0).Resize(tbl.Rows.Count - 1, tbl.Columns.Count).Select
End Sub

 33.  How To Merge and Unmerge Cells
Sub macro109()
