Introduction
Have you ever spent too much time on a repetitive task in an Excel worksheet trying to reorganise or format
data?
If this sounds familiar, then you need to know about macros. This course will show you how they can be
used to turn repetitive tasks into single clicks. You will learn how to record, edit and assign your macros to
workbooks, or worksheets, and start to explore what VBA, (Visual Basic for Applications) has to offer.
Macros or Visual Basic for Applications (VBA)?
What are macros and VBA?
Generally there is a lot of confusion when the words macro and VBA are mentioned, often in the same
sentence. A macro simply records mouse clicks as you go about a task and then converts the actions into
a VBA programming code. The advantage of this is that you can record a repetitive task once using a
macro and then play all the steps back again using a single mouse click.
To use macros you just need to understand the task you wish to record. If you want to look at the code and
alter it, you can, but you don’t have to, the macro does all the hard work for you. Macros can give you a
good insight into how VBA works, so if you would like to learn to write it at a later date, it will give you a
good starting point.
VBA is not just used in Excel, but is the building block for all the main office applications.
Writing your first macro
The macro recorder is able to record and playback every mouse click or keystroke you make. The process
works in three distinct phases.
1. Assign a name and shortcut key for your new macro, then start the macro recorder to record.
2. Perform the series of mouse clicks and keystrokes you wish to record (if it’s a long sequence it is a
good idea to plan this phase before you start to avoid errors).
3. Stop the recorder - don’t forget to do this otherwise you will end up with a very long macro!
Once you have completed these steps you can then play your macro using the shortcut key or review the
VBA code written by the macro.
Task 1
Write a simple macro
1. Open a new Excel workbook.
2. Select View  Macros  Record macro.
Figure 1

4
3. The macro dialogue box appears, type MyName into the macro
name box. (macro names must begin with a letter, no spaces
are allowed).
4. Type a lower case n into the Ctrl+ box.
5. Select This Workbook in the store macro drop down list
(the other options will be explained later).
6. Write a short description of what your macro does in the Description box.
7. Click the OK button then STOP and do nothing else! Figure 2
You are now recording your macro. There’s no time element to a macro recording so you can be relaxed.
However, the macro will now record every key press and mouse click, so it is important that you do not
press any keys or click anywhere with the mouse.
Record a macro that will put your name into the active cell
1. Type your name into the currently active cell, remember that every click and key stroke is recorded
so be careful not to move to any other cell. If you did your name would always appear in the cell
you moved to when the macro was played.
2. Press Ctrl + Enter, this saves the value to the cell without moving to the next line. This keystroke
combination is really useful when recording macros.
Stop the macro recording
You can do this in two ways:
1. click, View  Macros  Stop Recording or
2. click the Stop button on the bottom left of the
status bar
Figure 3
It is quite common for people to forget they are recording a macro and remember to stop it.
Test the macro
1. Click in any blank cell.
2. Click View  Macros  View Macros. The macro dialogue appears listing only the MyName
macro, as you have only recorded one macro so far.
3. Click the Run button. Your name should appear in the currently active cell.
4. Click in another blank cell and press Ctrl + n, once again your name appears in the active cell.
End task

5
Task 2
Practice writing some macros
Using the same work book, create macros to:
1. format text to font Arial Black, size 16 and centered
2. format a number to show 5 decimal places
3. write your name in cell C3
4. change the sheet colour to yellow and all text to red
5. save the workbook as Macros 1 - as the workbook contains macros you must select the Save as
type to Macro enabled workbook otherwise you will lose your
macros.
Figure 4
Task End
Choosing where to store macros
When you record a macro, Excel offers you three possible places to store it.
Each one determines which workbooks your macro will be available to and
who can access it. Therefore it is really important that you are aware of the
differences in the choices on offer.
Figure 5
The Workbook
If you select This Workbook as an option to store your macro then the macro you create will be available
to other workbooks as well, but only if the workbook containing the macro is open.
Personal Macro Workbook
The Personal Macro Workbook is a special workbook called Personal.xlsb. This is stored in a folder
called XLSTART buried deep in the file system where nobody is likely to find it and change it. Whenever
you open Excel, the Personal Macro Workbook opens in the background, but it is hidden so you never see
it. As it is always open every workbook has access to its macros at all times.
The main purpose of the Personal Macro Workbook is to act as a container to store macros that you want
to be available to every workbook. However, if you store macros in the Personal Macro Workbook they will
only work on your machine. If you email a piece of work that depends on one of these macros, it will not
work on the recipient’s machine. In this type of scenario you will want to store the macro in This
Workbook.
New Workbook
The New Workbook option is rarely used as it opens a new Excel file and the macro is only available in
this new file, hence you would always have to make sure that this file was open if you wanted to access the
macro.

6
Choosing macro shortcut keys
Excel provides many built in shortcut keys such a Ctrl + c to copy or Ctrl + v to paste. When you choose a
shortcut key combination to run your macro, if you select a combination that matches a built in shortcut
then your macro would override the built in shortcut; eg Ctrl + c would run your macro instead of copying
the selection.
There are several strategies to avoid causing clashes with the built in shortcut keys:
1. use capital letters for shortcut keys - this will result in a shortcut key of Ctrl + Shift + c which means
that you will still be able to copy using the Ctrl + c keystroke
2. run macros from the ribbon, as you did for your first macro,
View  Macros  View Macros
3. provide the user with buttons to run macros, something we will
cover later, together with…
4. adding a button to the quick access toolbar
Figure 6
Recording a macro with absolute references
Imagine this is a form you need to fill in every week. Every time
you make an expenses claim, you have to add your employee
number and other details.
This isn’t very efficient so you decide to create a macro to do the
job for you and complete the form with the required information.
This is an example of using absolute cell references as the
information must be put in cells B3, B5, B7, B9 and B11.
Figure 7
Task 3
Write a macro with an absolute reference
Open the Excel workbook, Expenses Claim – 1 from your m drive.
1. Begin recording a macro View  Macros  Record macro.
2. Name the macro FillInExpenseForm into the macro name box, always use mixed case or
underscore for the macro names rather than abbreviating as this can cause confusion.
3. Assign a shortcut key of Ctrl + e for the macro.
4. The macro only relates to this form and will only be used in this workbook, so choose the This
Workbook option for storing the macro.
5. Add a description to the macro so that other users will understand what it is used for and click OK.
6. Record the macro, start by making B3 the active cell.
This is a potential pitfall. If B3 is already the active cell when you begin recording the macro and
you simply type your name the recorder will place your name into whatever cell is the active cell
when the macro is run. This may not be B3.

7
For this reason you should click into a different cell and then back again into cell B3 to explicitly
record your intention to move the cursor to B3.
7. Fill in each box with fictitious details and remember to press the
Ctrl + Enter key after entering the last cell or you’ll stay in edit
mode and won’t be able to stop the macro recorder.
8. Click View  Macros  Stop Recording.
9. Now test your macro by running it from the ribbon or using the
shortcut key.
Figure 8
Understanding macro security
Macros are written using VBA which has access to most Windows system calls and executes automatically
when documents are opened. This makes it relatively easy to write a macro which could be hidden within a
Microsoft Office application, such as Word or Excel, which executes a virus when the document or
workbook is opened. This became one of the most common types of computer viruses and as a result,
applications running macros or VBA, now have improved features to make sure you are aware if macros
are present and allows you to choose to run them or not.
So whilst macros are a wonderful Excel feature they can also be very dangerous to your computer in many
ways. Macro security provides several methods to identify which macros you can trust and which you
can’t. Excel 2007 took a huge leap forwards in the battle against macro viruses. There used to be only
one Excel format, the .xls file, now there are two:
1. Excel Workbook with a .xlsx file extension. This can always be trusted because it is incapable of
storing a macro.
2. Excel Macro Enabled Workbook with a .xlsm file extension. You must ensure that you can trust
the origin of this type of workbook as it is capable of carrying destructive macro viruses.
Three ways to trust a macro enabled workbook
Excel provides three mechanisms for recognising a trusted workbook.
1. Place the workbook in a trusted folder. Excel allows you to designate a folder as a trusted location.
You are then able to open macro enabled workbooks that are saved to this location without
warnings or restrictions.
This is probably the easiest and best way to manage macro security.
2. Digitally sign the macro to confirm the identity of the author. Excel will also warn the recipient if it
has been changed since the author signed it.
Excel can be configured to run digitally signed macros from trusted publishes without warnings or
restrictions.
3. Warn the user before running a macro. Excel warns you that a workbook contains macros and
asks whether you wish to run them.

Saving marcros
Task 4
Saving your macros
1. Expenses Claim – 1 should still be open, try saving it as a regular Excel Workbook and you will get
the message below, which warns you that you cannot save it as a macro free workbook.
Figure 9
2. Click the No button to close the dialog.
3. This time change the Save as type to Excel
Macro Enabled Workbook (.xlsm).
4. Change the file name to Expenses Claim – 2 and click Save. Figure 10
5. Close the file.
Task end
Implementing macro security
When you open a macro enabled workbook, one of three things will happen.
1. The workbook opens without warnings and macros are enabled.
2. Excel displays a security warning, (this is the default setting).
3. The workbook opens without warning, but the macros are disabled. Figure 11
It doesn’t matter which is the case on your computer at the moment, the following task will teach you how to
set up the macro security options to any of the above.

9
Task 5
Setting the Trust Center’s macro settings
The Trust Center allows you to set the options of how you wish do deal with macros.
1. Click Office Button  Excel Options  Trust Center.
2. Click the Trust Center settings button.
3. Click Macro Settings in the left hand selection bar, this will display the macro settings.
Figure 12
4. This is where you can choose how macros are opened, the best option is probably the one already
selected, Disable all macros with notification.
5. Click OK and OK again.
6. Now open the Expenses Claim – 2 workbook
and the warning should be displayed.
7. Click on the Enable Content and a dialogue box
will be displayed asking if you wish to make this a
Trusted Document. Click Yes and now you will
be able to run your macro within the workbook.
Figure 13
Task end
Task 6
Set a trusted folder for your macros
This is probably the best method of all when dealing with macro security. If you designate a folder for your
trusted macro-enabled workbooks, Excel will know that they are trusted and not bother you with any
warnings.
For extra security, the trusted folder should always be a non-shared folder on your local hard drive ie (c:/),
not a network drive.

10
1. Create a folder for your trusted macro
enabled workbooks, eg c:/Trusted
Files.
2. Click Office Button  Excel Options
 Trust Center.
3. Click the Trust Center settings button.
4. Click the Trusted Locations on the left-
hand selection bar.
Figure 14
5. Click Add New Location button.
6. Click the Browse… button
7. Navigate to the folder that your trusted
files will be placed in.
8. Click the OK button
9. Click OK and OK again to close the
dialogues.
Figure 15
Test to see if the Trusted Folder works. Place the Expenses Claim – 2 workbook into the folder, now it
should open without warnings and the macro should still run.
Task end
Recording macros with relative references
The last example of an expense claim form was a useful example of a
macro involving absolute cell references, ie the cell references were always
the same locations.
However sometimes we need to be able to write a macro that uses relative
cell references to perform the same task at different places on the
worksheet or workbook.
For example the workbook on the right contains 88 companies, but it is in
the wrong format for a mail merge. We need the format to be as below.
Figure 16

11
This would take a long time to manually convert the records but a macro can do it in less than 5 seconds
using relative references.
Relative reference macros record an offset from the active cell. Imagine that the active cell is A4 (Alejandra
Camino). The relative macro will record the actions:
 move one cell down
 copy
 move one cell up and one to the right
 paste
…and so on until all of Alejandra’s details are moved to row 4. The macro will then delete the blank rows
and be ready to start again with the next person, Alexander Feuer.
Task 7
Record a macro with relative references
Open the workbook, Company List. First the macro recorder has to be told to use relative references. To
do this follow the steps below.
1. Click View  Macros  Use Relative References.
2. Make cell A4 the active cell. When recording a relative reference macro, it is vital that you select
the active cell before beginning the recording.
3. Click View  Macros  Record macro.
4. Call your macro MoveAddress with a shortcut of m (lower case).
5. Store the macro in This Workbook and click OK to begin recording the macro.
6. Click in cell A5 and Cut.
7. Click in cell B4 and Paste.
8. Continue until the complete
address is pasted into row 4.
Figure 17
9. Select rows 5:12.
10. Right click inside the selected cells and delete.
11. Click in A5 to make it the active cell. By placing the cursor in A5 before stopping recording it will
be in the right place to convert the next address when you run it many times.

12
Now you can convert the other 87 addresses by running the macro multiple times. Make A5 the active cell
then press Ctrl + m and let the keyboard automatically repeat. The next 87 addresses should be converted
very quickly and soon looks like this:
Figure 18
Save your work as a macro-enabled workbook called Company List – 2.
Task end
Using shapes to run macros
Running macros using the command keys you set up, or from the View menu are fine when it is your
workbook. However sometimes you may like to automate a workbook for a user and would like to make it
as simple as possible to do things such as print, perform a calculation or any other task you have assigned
to a macro.
The easiest way to do this is by creating a button and assigning a macro to that button and then all your
user has to do is click on that button to make the macro work.
Task 8
Assign a macro to a button
1. Open the Excel workbook Mortgage Calculator.
Excel can be easily modified to make interactive sheets that don’t even look like a spreadsheet.
Using this sheet we are going to record two macros to save and print as well as add a hyperlink to
the buttons.

13
2. Click View  Macros  Record macro.
3. Type PrintWorkbook in the macro name box.
4. Don’t assign a short cut and save the macro in
This Workbook.
5. Write a short description of what the macro does in the
description box.
6. Click the OK button.
7. Click the Quick Print button which will print out on the
default printer. Figure 19
Now you have your first macro of the workbook recorded, save your work as a macro enabled workbook
called Mortgage Calculator 2. This means if you mess up the second macro it is easy to go back to the
previous version without having to start again from the beginning.
1. Now record a macro called SaveWorkbook, completing the macro dialogue box as before except
for saving the workbook.
2. Click OK to start recording.
3. Click File  Save.
Now you have a macro that will save the workbook at a touch of a button, we just now need to add
the buttons now!
End task
Task 9
Add a shape to your worksheet
Although we are going to add shapes to the worksheet the same technique could be used with pictures or
clipart.
1. Resize the chart to make space for a row of buttons below it.
2. Click Insert  Illustrations  Shapes  Rectangles  Rounded Rectangle.
3. Click and drag on the worksheet to draw the button.
Figure 20
4. Click Drawing Tools  Format  Shape Styles  Shape Style Gallery  Blue - Accent 1.
5. Copy and Paste the shape twice and space them out underneath the chart.
6. Right click on the far right button and select Edit Text.

14
7. Type Save Quote to add a caption to the shape.
8. Add Print Quote and Go to Website to the other two buttons.
Figure 21
Connecting the macro to the shape
1. Right click the Save Quote shape.
2. Click Assign Macro on the shortcut menu.
3. Select the SaveWorkbook macro.
4. Click OK.
5. Now follow the same procedure to assign the PrintWorkbook macro to the Print Quote shape.
Connecting a hyperlink to a shape
1. Right click the Go to Website shape.
2. Click Hyperlink on the shortcut menu.
3. Click Existing File or Web Page on
the left hand selection bar.
4. Type http://www.essex.ac.uk into
the address box.
5. Click OK.
Figure 22
Now you can protect the worksheet and save it. Then reopen the workbook and test the buttons,
(remember to enable the macros when you reopen in).
Task end

15
VBA (the code behind the macros)
When you record a macro the sequence
of mouse clicks are automatically
converted into VBA code. If you open the
Visual Basic Editor you can actually
watch the code being written as you click
the mouse.
To add the developer tab to the ribbon
click File  Options Customize
Ribbon  Choose commands from
Macro  Developer  OK.
Figure 23
Now the Developer tab will be visible, click the Visual Basic Icon which brings up the VBA window.
Figure 24
Figure 25

16
Task 10
Record a macro and watch the VBA appear
1. Arrange the Excel window and the VBA window side by side.
Figure 26
2. Start recording the macro, call it ‘Test’, as soon as you press OK, go to
the VBA window and click on Modules  Module 1.
You will now see your macro.
Figure 27
3. In Excel, select the whole worksheet, change the
background, type some text and format it. When
you have finished, stop the macro. You should
now be able to look at the code and match it to
what actions you performed with the mouse.
