1. What is VBA and what you can do with it?
Visual Basic for Applications (VBA for short) is a programming
environment designed to work with Microsoft’s Office applications
(Word, Excel, Access, and PowerPoint). Components in each application
(for example, worksheets or documents) are exposed as objects to the
programmer to use and manipulate to a desired end. Almost anything you
can do through the normal use of the Office application can also be
automated through programming.
Microsoft Visual Basic for Applications (VBA) is an embeddable
programming environment designed to enable developers to build custom
solutions using the full power of Microsoft Visual Basic.
2. Developers using applications that host VBA can automate and extend the
application functionality, shortening the development cycle of custom business
Visual Basic for Applications (VBA) is an implementation of Microsoft's event-
driven programming language Visual Basic, and associated integrated development
environment (IDE), which is built into most Microsoft Office applications.
As its name suggests, VBA is closely related to Visual Basic, but can normally only
run code within a host application rather than as a standalone application.
VBA is a complete programming language, but you can’t use it outside the
application in which it is integrated. This does not mean VBA can be integrated
only with Office programs. Any software vendor that decides to implement VBA
can include it with their application.
3. VBA is relatively easy to learn, but to use it in a new application, you must first become familiar with the
object model of the application. For example, the Document and Dictionary objects are specific to the
Word object model, whereas the Workbook, Worksheet, and Range objects are specific to the Excel object
model. You use VBA to automate operation in the application that support it.
As a beginning language, VBA will suit your needs well. VBA is not as vast as many
popular languages because such extensiveness is simply unnecessary. VBA was built to
work with and extend the abilities of Office applications, so it doesn’t need the
substance of a programming language used to build full-blown applications from
scratch. The relative simplicity of VBA makes it less intimidating and easier for you to
learn. VBA, however, does share many of the programming constructs common to all
languages, so it also serves as a great introduction to programming.
4. What is a macro?
If you perform a task repeatedly in Word or Excel , you can automate the task by using a
macro. A macro is a series of steps that is grouped together as a single step and then
executed when necessary.
Macro is the sequence of command you can repeat at will .you can repeat the action by
using a single command to run macro.
A macro is a tool that allows you to automate tasks and add functionality to your
forms, reports, and controls. For example, if you add a command button to a form, you
associate the button's On Click event to a macro, and the macro contains the commands
that you want the button to perform each time it is clicked.
The term macro is often used to refer to standalone macro objects (that is, the objects
that you see under Macros in the Navigation Pane), but in reality, one macro object can
contain multiple macros. In that case, it is referred to as a macro group. A macro group
is displayed in the Navigation Pane as a single macro object, but a macro group actually
contains more than one macro. Of course, it is possible to create each macro in a
separate macro object, but often it makes sense to group several related macros into a
single macro object. The name in the Macro Name column identifies each macro.
5. The easiest way to create a macro in Excel is by recording your steps with Excel’s
macro recorder. For example, if you would like to automate a task in Excel, you
record yourself performing the task by turning on a little virtual tape
recorder, which will record each step as you enter it. When you are finished
entering your steps, you turn off the recorder.
Here are the basic steps for recording a macro:
1. Turn on the macro recorder.
2. Enter a name for the macro.
3. Indicate a desired shortcut key for the macro (optional).
4. Indicate where you want the macro to be stored.
5. Enter a description for the macro (optional).
6. Start the recorder.
7. Enter your steps.
8. Stop the recorder.
6. Once you have recorded a macro, you can run your macro in one of two ways:
1. If you assigned your macro to a key combination, you can press that key
combination at any time to run the macro.
2. Whether or not you assigned your macro to a key combination, you can access
your macro from the ribbon. You’ll display a macro list, choose the macro you want
to run, and then choose Run.
We’ll go through each of these steps of recording and running macros and learn
what they mean, while actually recording some real-life macros.
Displaying the Developer Ribbon
Macro making is made much easier with the use of the Developer ribbon, a special
toolbar designed to help you with creating, running, and revising your macros. You
can access some of the macro commands from the View toolbar, but you’ll find
your macro experiences will be much easier if you have the Developer ribbon on
7. The first macro we’re going to create is a simple macro that places your name in a cell. Usually
when we record macros, we try to record a task that we expect to use over and over again. The
easiest way to quickly create a simple macro in Word or Excel is to use the macro recorder. The
Macro Recorder creates a copy of the commands you select with your mouse.
So for our first macro, here are the steps to follow—all the steps:
1. With your Excel open ,place pointer in cell A1.This way, we’ll all be in exactly the same place when
we start recording this macro.
2. Click the Developer tab to open the Developer ribbon.
3. Click the Record Macro option on the ribbon.
4. In the Record Macro dialog box, enter NAME1 as the name of this macro.
5. In the Shortcut Key field, hold down the shift key and type n so that ctrl+shift+n will be the
keyboard shortcut for this macro.
6. In the Store Macro In field, choose “Personal Macro Workbook.” This is the universal workbook
that is accessible by all Excel spreadsheets.
7. Enter an optional Description for this macro.
8. Click OK. The macro recorder is now running and will record all of your keystrokes.
9. Back in the spreadsheet, in cell A1, enter your name as you wish to record it in this macro, leaving a
space between each word.
10. Press enter when you have finished entering your name.
11. Click the Stop Recording option on the Developer ribbon
8. Figure 2- 1 Recording a macro
9. When you created your three NAME macros, you were given three options for saving
the macros. We chose to save all three of the macros to the Personal Macro Workbook.
For example, a Word macro that would quickly format a header and footer with the
date, time and page number would be saved so that all Word files could execute the
macro, not just one file.
Saving to the Personal Macro Workbook
You’ll find that when you attempt to close Excel, you will receive a message asking if
you want to save the changes you made to your Personal Macro Workbook. If you click
Yes, your macros will be saved and available to you the next time you open Excel.
The Personal Macro Workbook is a hidden workbook, not normally accessible as a
workbook you can view.
Saving to This (the Current) Workbook
Another option is to save the macros to this workbook. Some macros relate to specific
workbooks and aren’t of use in other workbooks.
For example, if you create a macro that offers the user the option of performing certain
calculations on the data in an existing workbook, and the calculations relate only to that
10. When you choose to save a macro to your current workbook, you must also save
the workbook in order to keep the macro.
When you are ready to save a workbook that contains a macro, you must choose
Macro-Enabled Workbook as your workbook type.
When the Save As window appears, follow these steps:
1. Choose the folder where you want to save the workbook in the Save In
2. Enter the workbook name in the File Name field.
3. Choose Excel Macro-Enabled Workbook in the Save as Type field.
4. Click Save
11. Figure 2.2 Saving a worksheet that contains macros
12. The third option is to save a macro to a new workbook. Some people want to create
macros that are available to them for use in other workbooks, but they don’t want to
make them available universally through the Personal Macro Workbook.
By saving macros in a new workbook, you choose when you want the macro to be
available by simply opening that workbook.
As soon as you choose to save your macro to a new workbook, Excel opens a new
workbook on your screen. Excel gives the new workbook the name Book followed
by a number.
When you want to use the macro that has been saved to a new workbook, you must
open that workbook. As long as that file is open, your macro will be available to all
Excel workbooks that are open on your computer.
13. If the macro has not been assigned to a keyboard command or a toolbar then
do the following to run the macro;
1. Tools, Macro, Macros
2. Under Macro Name, click the macro you want to run
3. Click the Run button

20. To delete a macro, you use the VBA
1. Open the workbook that contains the macro you want to delete.
2. On the Tools menu, point to Macro, and then click Macros.
3. In the Macros in list, click This Workbook.
4. In the Macro name box, click the name of the macro that you want to delete.
5. Click Delete
21. Exploring the Visual Basic Editor in Excel
If you use Excel a lot, you are familiar with its spreadsheet layout. The menu bar
has changed considerably in Excel 2007 and now uses interactive ribbon controls
for the submenu structure instead of the menu structure that previous users were
Fortunately, the Visual Basic Editor (VBE) window has stayed much the same as
in older versions of Excel, so if you have used Excel 2003 to design VBA code, you
will not find too many differences.
You can insert data and formulas into the cells, format the cells or the entire
worksheet, and insert graphics and graphs. You may even have tried recording a
macro by clicking on the Developer item in the menu bar and clicking on the
Record Macro icon in the Code control of the ribbon.
22. Most users are unaware that, in addition to the spreadsheet application of Excel,there is
an extremely powerful programming language built into Excel that you can use to
design your own applications.
A macro is a procedure written in VBA code that performs certain tasks.
However, before you can start programming in Excel, you need to know where the
macros are stored. This is not as obvious as it used to be when text-based macros were
entered into a special macro spreadsheet. In the old macro language, you simply inserted
a macro sheet and entered your commands anywhere. Now that the macro language has
grown and become a full object-oriented language, the method of storing it has also
Macros are now kept inside hidden VBA projects that are stored and saved within the
The language works in conjunction with object structures and hierarchies, and you can
even create your own objects by using class modules.
These VBA projects can be accessed through a companion program called the Visual
Basic Editor (VBE). Press ALT-F11 to see the window shown in Figure 2-1.
23. Figure 2-1
24. At first glance, this window with its new menu bar, containing menus for
File, Edit, View,Insert, Format, Debug, Run, Tools, Add-Ins, Window, and Help, might be confusing.
It opens as a separate application window, but it is still very much a part of the Excel application. In
fact, this window opens up a whole new ball game in terms of what you can do with Excel.
In the next section, I’ll explain the windows in more detail.
VBA Project Explorer and Code Windows
The Project Explorer, which shows a Project tree, is in the left-hand side of the screen, just below
the menu and toolbar.
It shows the VBA project for the active workbook as it stands, displaying the details in tree form so
that you can easily navigate between them.
If you click a branch of the tree, you’ll enter that particular workbook or worksheet from the Visual
The VBA project is the root of the tree, and the workbook and worksheet objects are
the branches coming off the tree. As you add and delete worksheets or workbooks, the
You can also add in other objects such as UserForms and modules.
25. Remember, VBA is an object-oriented language. The first branch on the tree
coming from the root of the VBA project says Microsoft Excel Objects. Coming off
this branch are objects for the workbook that contain worksheets.
This is a very important concept to understand because the workbook is an object
that can be referred to, and each sheet is also an object that can be referred to.
Double-click ThisWorkBook, and the code window for the Workbook object will
The code window automatically shows the statements
PrivateSub Workbook_Open() and End Sub:
L 1-1 Private Sub Workbook_Open()
This gives you a code area to write your VBA code against the Workbook_Open

27. To edit a macro, you use the VBA
1. On the Developer tab, under Visual Basic, click Macros.
2. In the list, click the macro that you want to edit, and then click Edit.
The Visual Basic Editor opens.
3. Make the changes that you want.
