Introduction to Programming in Excel

Have you ever been tired of doing a task in Excel which you feel can be automated and save your time? Most of the time, you must have encountered such tasks. However, in order to automate any task, you first need to have programming skills for that particular language. In Excel, you can do programming with the help of Visual Basic for Application (VBA) which is Excel’s own programming language that can help you to automate the tasks. In this article, we will see how we can do programming in Excel VBA. VBA can be used to write a program that can automate the task for you. The piece of lines we write under VBA is called Macro, which is written in such a way that they instruct the Excel system about what to be done.

How to Program in Excel?

Let’s understand how to Program in excel with few illustrations.

Enabling Developer Tab

The first thing that comes is enabling the developer tab that helps you to record and store a macro (VBA Code). Let us see how we can get that enabled.

  • Navigate to the File menu in your excel file and click on it.

Programming in excel 1-1

  • Within the File menu, click on Options, and it will load a new window with all excel options available.

Programming in excel 1-2

  • In the new window that popped up named Excel Options, click on the Customize Ribbon tab. You can see all the customization options you can use for Excel Ribbon, which appears at the top of your Excel file.

  • Enable Developer option under Main Tabs dropdown within Customize the Ribbon: section. You can check (tick-mark) the Developer tab to enable it. Click the OK button placed at the bottom right of the Excel Options tab, and that’s it.

Programming in excel 1-3

  • You have successfully enabled the Developer option within your excel. If you check the Excel Ribbon in your file now, you’ll be able to see a new tab added there with the name Developer on it.

Developer Tab-program excel

This is the first step you need to follow before you start writing macros in Excel. Because the Developer tab is needed to record and run the macro, this option tab is not by default enabled, which is why we tried enabling it here first.

Recording a Macro

  • Open the Excel file. Navigate towards the Developer tab you just enabled and then click on the Record Macro button, categorized and can be seen under the Code section.

Programming in excel 2-1

  • As soon as you click on the Record Macro button, you’ll see a window popping up; in that window, you must have to assign a name to the macro; you can also assign a shortcut key for this macro to run. Can you add the description, if any, for this macro you are creating? Once you are done with all this, you can click on the OK button placed at the right bottom of the window. See the screenshot below for your reference.

Record Macro

As soon as you click OK, the system starts recording the macro and all the tasks you perform will be recorded and converted to Excel Program in the backend.

  • Try typing the sentence “This is my first VBA code, and I am very happy!” in cell A1 within the Excel sheet and press Enter key. These steps will be recorded in the backend of the macro.

  • Under the Code section, you might have observed that the Record Macro button has changed to Stop Recording. This is like Play and Stop. Record Macro Works as Play button and Stop Recording work as Stop button. Click on the Stop Recording button to stop the recording.

Stop Recording

The magic behind all this is, Excel has recorded my steps here and converted those into pieces of code so that this task can be automated. It means, every single step, selecting cell A1, inputting the text as “This is my first VBA code, and I am happy!”, clicking Enter to go to the next cell. All these steps are converted into a VBA code. Let’s check the code now.

  • In order to go to Visual Basic Editor, you can click on the Visual Basic option under the Code category in the Developer tab, or you can use Alt + F11 as a shortcut for the same.

Visual Basic

  • Navigate towards the Modules section under VBAProject and click on the plus button under it to see the list of active modules in VBA.

Module 1

  • Inside the Modules folder, you can see Module1 as soon as you click on the plus sign. You can double click on Module1; it is where your code for the task we performed in previous steps (Step 3 and 4) are recorded. Save this code, and you can run it every time to get the same output. See the screenshot below:

Conclusion

  • We can record a macro in Excel to automate day to day small tasks, which are simpler for the system to manipulate programmatically.
  • The cool thing about it is you don’t need to dig your head deep for the logic behind each step you perform. Excel VBA does it for you.
  • For some complex tasks, such as the one which involves looping and conditional statements, you need to write code manually under VBA.

Things to Remember About Programming in Excel

  • The Developers tab is not by default enabled and visible to you in Excel Ribbon. You need to enable it through Excel Options.
  • Recording a macro works on simple tasks that are repeating, and you need those to be automated. However, for complex tasks which involve looping or Conditional Inputs and Outputs are still need to be coded manually under VBA.
  • You need to save the file as an Excel-Macro Enable file format in order to be able to read and run the code again on your excel.

What is Programming in Excel?

Programming refers to writing a set of instructions that tell Excel to perform one or more tasks. These instructions are written in the Visual Basic for Applications (VBA) as this is the language understandable to Excel. To write an instruction, one can either write a code in VBA or record a macro in Excel. A macro is recorded to automate repetitive tasks. When a macro is recorded, VBA generates a code in the background.

For example, to submit an Excel report, a table needs to undergo the same set of tasks each time. These tasks include applying a pre-defined border, color, alignment, and font. To program in Excel, a macro can be recorded for performing all these tasks.

The purpose of programming in Excel is to save the user from performing the same tasks again and again. Moreover, it helps accomplish multiple tasks at a great speed that would have taken a lot of time, had they been performed manually.

Stages of Programming in Excel VBA

Programming in Excel VBA is carried out in the following stages:

  1. Enable the Developer tab in Excel
  2. Record a macro in Excel
  3. View and examine the VBA code generated by the recorded macro
  4. Test the VBA code of the recorded macro
  5. Save the recorded macro (or the VBA code)

Further in this article, every stage of programming ine xcel has been discussed one by one. The steps to be performed in each stage are also listed.

Stage 1–Enable the Developer Tab in Excel

Let us understand how to enable the Developer tabEnabling the developer tab in excel can help the user perform various functions for VBA, Macros and Add-ins like importing and exporting XML, designing forms, etc. This tab is disabled by default on excel; thus, the user needs to enable it first from the options menu.read more in Excel. This tab is enabled to record a macro and access VBA. When the Developer tab is enabled, it appears on the Excel ribbonRibbons in Excel 2016 are designed to help you easily locate the command you want to use. Ribbons are organized into logical groups called Tabs, each of which has its own set of functions.read more. However, by default, Excel does not display the Developer tab.

Note: To know an alternate method to record a macro and access VBA, refer to the “alternative to step 1” in stages 2 and 3.

The steps to enable the Developer tab in Excel are listed as follows:

Step 1: Go to the File tab displayed on the Excel ribbon.

Programming in Excel Example 1

Step 2: Select “options” shown in the following image.

Example 1.1

Step 3: The “Excel options” window opens, as shown in the following image. Select “customize ribbon” displayed on the left side of this window.

Programming in Excel Example 1.2.0

Step 4: Under “choose commands from” (on the left side of the window), ensure that “popular commands” is selected. Under “customize the ribbon” (on the right side of the window), choose “main tabs” from the drop-down list.

Next, select the checkbox of “developer” and click “Ok.” This checkbox is shown in the following image.

 Example 1.3.0

Step 5: The Developer tab appears on the Excel ribbon, as shown in the following image.

Programming in Excel Example 1.4

Stage 2–Record a Macro in Excel

Let us learn how to record a macroRecording macros is a method whereby excel stores the tasks performed by the user. Every time a macro is run, these exact actions are performed automatically. Macros are created in either the View tab (under the “macros” drop-down) or the Developer tab of Excel.

in Excel. When a macro is recorded, all tasks performed by the user (within the workbook) are stored in the Macro Recorder until the “stop recording” option is clicked. Apart from Microsoft Excel, a macro can be recorded for all Office applications that support VBA.

The steps to record a macro in Excel are listed as follows:

Step 1: From the Developer tab, click “record macro” from the “code” group.

Alternative to step 1: One can also click “record macro” from the “macros” group of the View tab of Excel.

how to record macros in excel Example 1.5

Step 2: The “record macro” window opens, as shown in the following image. In this window, one can name the macro before recording it. The default macro name given by Excel is “macro1.”

The rules governing a macro name are stated as follows:

  • It should not contain any space ( ), period (.) or exclamation point (!).
  • It cannot contain any special characters (like $, @, ^, #, *, &) except the underscore (_).
  • It should not begin with a numerical value. Rather, it must start with a letter.
  • It cannot exceed 255 characters in length.

Note: It is recommended to use short and meaningful names for macros. Further, one must assign a unique name to each macro. In VBA, two macros within the same code module cannot have the same names.

how to record macros in excel Example 1.7

Step 3: In the “macro name” box, we have entered the name “recording_macro.”

Notice that an underscore has been used as a separator between the two strings (recording and macro) of the name. No spaces, periods or special characters have been used in this name.

 how to record macros in excel Example 1.8

Step 4: Click “Ok” to start recording the macro. Once “Ok” is clicked in the preceding window, the “record macro” button (in the Developer tab or the View tab) changes to the “stop recording” button.

Next, carry out the tasks to be recorded in the macro “recording_macro.”

Note: Since the Macro Recorder records every action performed by the user, ensure that the actions are executed in the right sequence. If the recorded sequence is correct, Excel will perform the tasks efficiently each time the macro is run.

However, if a sequencing error occurs, one must either re-record the actions or edit the VBA codeVBA code refers to a set of instructions written by the user in the Visual Basic Applications programming language on a Visual Basic Editor (VBE) to perform a specific task.read more manually. If one is recording the macro for the first time, it is recommended to keep a copy of the workbook to prevent any undesired changes to the stored data.

In the following steps (step 4a to step 4c), the tasks to be recorded have been performed.

Step 4a: Select cell A1 of the worksheet. This is the first task that is recorded. The selection is shown in the following image.

how to record macros in excel Example 1.9

Step 4b: Type “welcome to VBA” in cell A1. This is the second task that is recorded. Exclude the beginning and ending double quotation marks while typing.

Example 1.10.0

Step 4c: Press the “Enter” key. As a result, the selection shifts from cell A1 to cell A2. This becomes the third task that is recorded.

The selection is shown in the following image.

Example 1.11

Step 5: Click “stop recording” in the “code” group of the Developer tab. By clicking this option, Excel is told to refrain from recording any further tasks.

The “stop recording” option is shown in the following image.

Programming in Excel Example 1.12.0

Stage 3–View and Examine the VBA Code Generated by the Recorded Macro

Let us observe and study the VBA code generated by the macro recorded in stage 2. Remember that one can either directly write a code in the Visual Basic Editor (VBE or VB Editor) or let a macro do the same.

The VBE is a tool or program where VBA codes are written, edited, and maintained. When a macro is recorded, a code is automatically written in a new module of VBE. Note that VBA is the programming language of Excel.

The steps to view and study the code generated by the recorded macro are listed as follows:

Step 1: Click “visual basic” from the “code” group of the Developer tab. This option is shown in the following image.

 Example 1.13

Alternative to step 1: As a substitute for the preceding step, press the keys “Alt+F11” together. This is the shortcutAn Excel shortcut is a technique of performing a manual task in a quicker way.read more to open the VBE window.

Note: “Alt+F11” is a toggle key which when pressed repeatedly, helps to switch between VBE and Excel.

Programming in Excel Example 1.14

Step 2: The Visual Basic Editor window opens, as shown in the following image.

To the left of the VBE window, the worksheet, workbook, and module are shown. This window on the left (named “Project-VBAProject”) is also known as the Project window or the Project Explorer of VBE.

how to record macros in excel 1.15.0

Step 3: Double-click “modules” shown in the following image.

Note: “Modules” are folders shown in the Project window after recording a macro. They are not shown prior to recording a macro. “Modules” are also shown when a module is inserted manually from the Insert tab of the VBE.

Programming in Excel Example 1.16

Step 4: Double-click “module1” under modules. A code appears on the right side of the VBE window. This window on the right [named “Book1-Module1 (Code)”] is known as the module code window.

The code is displayed in the following image.

Note: The code generated by recording a macro can be checked in the “modules” folder (in the module code window). In a module code window, one can also write a code manually or copy-paste it from another source.

 how to record macros in excel Example 1.17

In the following steps (step 4a to step 4d), the code generated by the recorded macro has been studied.

Step 4a: The first word of the code is “Sub.” “Sub” stands for subroutine or procedure. At the start of the code, the word “Sub,” the macro name (recording_macro), and a pair of empty parentheses are displayed. This is followed by the statements to be executed by the code. These statements are:

ActiveCell.FormulaR1C1 = “Welcome to VBA”

Range (“A2”). Select

The code ends with “End Sub.”

The start or head [Sub Recording_Macro ()] and the end or tail [End Sub] of the code are shown in the following image.

Note 1: The words “macro” and “code” are often used interchangeably by several Excel users. However, some users also distinguish between these two words.

A VBA code is a command created either by writing a code directly in VBE or by recording a macro in Excel. In contrast, a macro consists of instructions that automate tasks in Excel. According to one’s choice, one can decide whether or not to differentiate between the two words.

Note 2: The “Sub” can be preceded by the words “Private,” “Public,” “Friend,” or “Static.” All these words set the scope of the subroutine. The default subroutine used in VBA is “Public Sub.” So, when “Sub” is written in a code, it implies “Public Sub.”

A “Public Sub” can be initiated by subroutines of different modules. However, a “Private Sub” cannot be initiated by subroutines of other modules.

how to record macros in excel Example 1.18

Step 4b: The first activity we performed (in step 4a of stage 2) was to select cell A1. Accordingly, the following statement of the code tells Excel that the active cell is R1C1.

ActiveCell.FormulaR1C1

When a macro is recorded, VBA uses the R1C1 style for referring to cells. In this style, the letter R is followed by the row number and the letter C is followed by the column number. So, cell R1C1 implies that the row number is 1 and the column number is also 1. In other words, cell R1C1 is the same as cell A1 of Excel.

Step 4c: The second activity we performed (in step 4b of stage 2) was to type “welcome to VBA” in cell A1. So, the following statement of the code tells Excel that the value in cell R1C1 is “welcome to VBA.”

ActiveCell.FormulaR1C1 = “Welcome to VBA”

Step 4d: The third activity we performed (in step 4c of stage 2) was to press the “Enter” key. By pressing this key, the selection had shifted from cell A1 to cell A2. Therefore, the following statement tells Excel to select cell A2.

Range (“A2”). Select

This is the way VBA generates a code for all the activities performed under stage 2 of programming in Excel. Examining the code line-by-line makes it easier to interpret it.

Stage 4–Test the VBA Code of the Recorded Macro

Let us test the code when it is run multiple times. Note that a macro (or code) can be run as many times as one wants. Each time it runs, it performs the recorded tasks in Excel.

The steps to test the code that we examined in stage 3 are listed as follows:

Step 1: Delete the string “welcome to VBA” from cell A1 of Excel. Let A1 remain as a blank, selected cell. The following image shows the empty cell A1.

Note: To go back from VBE to Excel, press the toggle key “Alt+F11.”

how to record macros in excel Example 1.19

Step 2: Go to VBE again by pressing the key “Alt+F11.” Click anywhere within the code. Next, click the “Run Sub/UserForm (F5)” button. This button is shown within a blue box in the following image.

Note: Alternatively, one can press the key F5 to run the VBA code.

Programming in Excel Example 1.20.1

Step 3: The output is shown in the following image. The preceding code enters the string “welcome to VBA” in cell A1. Thereafter, the selection shifts to cell A2. The string “welcome to VBA” has been entered in cell A1 because this cell was selected (in step 1) before running the code.

Each time the code is run, the currently selected cell (or the active cell) is filled with the string “welcome to VBA.” Then, the selection shifts to cell A2. So, if cell M10 is the active cell, running the code fills this cell with the stated string and selects cell A2 at the end.

However, had cell A2 been selected, running the code would have filled this cell with the string “welcome to VBA.” Moreover, in the end, cell A2 would have remained the selected cell.

Example 1.21.0

Stage 5–Save the Recorded Macro (or the VBA Code)

Let us learn how to save a workbook containing a recorded macro. If a macro is saved, its VBA code is also saved.

The steps to save a workbook containing a macro (or a VBA code) are listed as follows:

  1. Click “save as” from the File tab of Excel. The “save as” dialog box opens, as shown in the following image.
  2. Assign a name to the Excel workbook in the “file name” box. We have entered the name “macro class.”
  3. Save the workbook with the “.xlsm” extension. So, in the “save as type” box, choose “Excel macro-enabled workbook.”
  4. Click “save” to save the workbook.

A workbook containing a macro should always be saved with the “.xlsm” extension. This extension ensures that the macro is saved and can be reused the next time the workbook is opened.

Note 1: The “save as” command is used when a workbook is saved for the first time. It is also used when a new copy of the workbook is to be created and, at the same time, the original copy is to be retained as well.

Note 2: If the workbook containing a macro is saved as a regular workbook (with the “.xlsx” extension), the macro will not be saved. Further, one may lose the code of the recorded macro. 

 Example 1.23.0

Frequently Asked Questions

1. What is programming and how is it carried out in Excel?

Programming refers to instructing Excel to perform one or more tasks. To instruct Excel, either a code can be written in the Visual Basic for Applications (VBA) or a macro can be recorded in Excel. Each time a macro is recorded, a code is generated by VBA in the background.

The steps to carry out programming in Excel are listed as follows:

a. Enable the Developer tab in Excel.
b. Record a macro in Excel. For recording, perform each activity in the sequence in which it should be recorded.
c. Save the code generated by the recorded macro and run it whenever required.

One can also carry out programming by writing a code manually and then saving and running it.

Note: To learn the details of programming in Excel, refer to the description of the different stages given in this article.

2. How to write a code for programming in Excel?

For programming in Excel, a code is written in Visual Basic Editor (VBE), which is a tool of VBA. The steps to write a code in VBE are listed as follows:

a. Open a blank Excel workbook.
b. Press the keys “Alt+F11” to open VBE.
c. Select any worksheet from “Microsoft Excel Objects” listed in the “Project-VBA Project window.”
d. Click the Insert tab and choose “module.” A folder named “modules” and an object named “module1” are created in the “Project-VBA Project window.” At the same time, a window opens on the right, which is titled “Book1-Module1 (Code).”
e. Enter the code in the “Book1-Module1 (Code)” window that has opened in the preceding step.
f. Click anywhere within the code once it has been written entirely.
g. Run the code by pressing F5 or clicking the “Run Sub/UserForm (F5)” button.

If the code has been entered correctly in step “e,” Excel will perform the tasks it has been instructed to. However, if there is an error in the code, an error message will appear.

Note: For saving a code, refer to stage 5 of programming in Excel given in this article.

3. How to learn programming in Excel?

To learn programming, one can learn how to record a macro in Excel. It is easier to learn macro recording than to create a code manually in VBE. Moreover, macro recording can be done even if one does not know VBA coding.

However, each time a macro is recorded, examine the generated code carefully. As one becomes proficient in macro recording, the codes too will become understandable. In this way, learning programming in Excel will no longer be a complicated task.

excel cell referenceProgramming in Excel is simpler than you may think. The VBA editor and built in programming functions in Excel make creating your own routines and programs easy. This tutorial will show you how to create your own Inventory Input form so that a user can add stock to the worksheet. This tutorial requires a basic knowledge of Excel. For a great introduction to Excel, enroll in the Microsoft Excel 2013 Basics course now. This course contains lessons that will teach you how to identify parts of the worksheet. You will learn how to select cells and enter data. The course will show you how to change column widths and row heights. You will learn to work with various elements of the worksheet and you will learn to work with charts.

Let’s start by creating our button to launch our form.

Programming in Excel – Creating a Command Button

Command buttons are a great way to launch programs you create for your Excel spreadsheets. They are also a great way to launch the VBA editor. To create a command button, click the Developer tab on the main Excel ribbon and select “Insert” and choose “Command Button” under the ActiveX controls.

Drag your Command button using the handles to size the button. When you are happy with the size and shape, make sure you have “Design Mode” clicked and then double click the button to launch the VBA editor panel within Excel.

Create the Stock Entry Form

We are going to create a Stock Entry form for our worksheet. To create a new form, select “Insert” and then select “UserForm” to insert a new user form:

ProgrammingInExcel1

When you add a new form, a new Toolbox opens to allow you to add your own controls to the form. This toolbox allows you to add labels, text boxes, combo boxes and other controls that you use to control the information on your form:

ProgrammingInExcel2

The form and each control or element on the form has properties. These properties allow you to change the appearance of the element as well as other properties:

ProgrammingInExcel3

Notice that in the above properties we have renamed the form to “StockForm.” It is important to name all of your elements with clearly defined names to make it easier when you start to create your Excel program.

Let’s add some controls and elements to our stock form.

Add the Input Boxes to Your Stock Form

Our stock form will allow users to add stock to an inventory form. Our form will require the user to enter the date, the user name, the item and the number of stock items so we will add input boxes for each of them.

To create an input box for the date, insert a text box and call it “newDate.” Insert a label for the text box and change the caption property of the label to date:

ProgrammingInExcel4

Create a combo box for the Item to be entered. A combo box will allow the user to either enter a stock item or choose a stock item from a drop down list. To create the drop down list, define the row source property of the combo box as a named range from your worksheet. For the tutorial we named the items as Inventory and then specified “Inventory” under the row source property:

ProgrammingInExcel5

Don’t forget to name the Item Combo box “newItem.”

Now add a combo box for the user. Change the user element name to “newUser” and use “Users” as a named range to create a row source for the users in the worksheet.

We will add a text box element for the number of stock items. Name the text box “newTotal.”

Now we can add another command button to allow users to add the items to the worksheet. Create a command button on the form. Double click the button to open the VBA editor for the button.

The course includes lessons on Excel VBA and even includes an Excel VBA cheat sheet.

Add the Code

To add each new inventory item to the list, we first need to find the next new row in our worksheet. If we don’t search for the next new row, then our button will add the information to the same line over and over again and overwrite the information.

To find the next new row, use the following code:

newRow = Sheet2.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Row

The above code finds the next row in a worksheet and stores the value in the variable called “newRow.” We are going to use this value to enter the new inventory using the following code:

Cells(newRow, 1).Value = newDate.Text

Cells(newRow, 2).Value = newUser.Text

Cells(newRow, 3).Value = newItem.Text

Cells(newRow, 4).Value = newTotal.Text

The above code inserts the values from the form into the cell with the address (newRow,1) to (newRow,4).

This is what our worksheet looks like:

Excel VBA Tutorial – How to Write Code in a Spreadsheet Using Visual Basic

Introduction

This is a tutorial about writing code in Excel spreadsheets using Visual Basic for Applications (VBA).

Excel is one of Microsoft’s most popular products. In 2016, the CEO of Microsoft said  «Think about a world without Excel. That’s just impossible for me.” Well, maybe the world can’t think without Excel.

  • In 1996, there were over 30 million users of Microsoft Excel (source).
  • Today, there are an estimated 750 million users of Microsoft Excel. That’s a little more than the population of Europe and 25x more users than there were in 1996.

We’re one big happy family!

In this tutorial, you’ll learn about VBA and how to write code in an Excel spreadsheet using Visual Basic.

Prerequisites

You don’t need any prior programming experience to understand this tutorial. However, you will need:

  • Basic to intermediate familiarity with Microsoft Excel
  • If you want to follow along with the VBA examples in this article, you will need access to Microsoft Excel, preferably the latest version (2019) but Excel 2016 and Excel 2013 will work just fine.
  • A willingness to try new things

Learning Objectives

Over the course of this article, you will learn:

  1. What VBA is
  2. Why you would use VBA
  3. How to get set up in Excel to write VBA
  4. How to solve some real-world problems with VBA

Important Concepts

Here are some important concepts that you should be familiar with to fully understand this tutorial.

Objects: Excel is object-oriented, which means everything is an object — the Excel window, the workbook, a sheet, a chart, a cell. VBA allows users to manipulate and perform actions with objects in Excel.

If you don’t have any experience with object-oriented programming and this is a brand new concept, take a second to let that sink in!

Procedures: a procedure is a chunk of VBA code, written in the Visual Basic Editor, that accomplishes a task. Sometimes, this is also referred to as a macro (more on macros below). There are two types of procedures:

  • Subroutines: a group of VBA statements that performs one or more actions
  • Functions: a group of VBA statements that performs one or more actions and returns one or more values

Note: you can have functions operating inside of subroutines. You’ll see later.

Macros: If you’ve spent any time learning more advanced Excel functionality, you’ve probably encountered the concept of a “macro.” Excel users can record macros, consisting of user commands/keystrokes/clicks, and play them back at lightning speed to accomplish repetitive tasks. Recorded macros generate VBA code, which you can then examine. It’s actually quite fun to record a simple macro and then look at the VBA code.

Please keep in mind that sometimes it may be easier and faster to record a macro rather than hand-code a VBA procedure.

For example, maybe you work in project management. Once a week, you have to turn a raw exported report from your project management system into a beautifully formatted, clean report for leadership. You need to format the names of the over-budget projects in bold red text. You could record the formatting changes as a macro and run that whenever you need to make the change.

What is VBA?

Visual Basic for Applications is a programming language developed by Microsoft. Each software program in the Microsoft Office suite is bundled with the VBA language at no extra cost. VBA allows Microsoft Office users to create small programs that operate within Microsoft Office software programs.

Think of VBA like a pizza oven within a restaurant. Excel is the restaurant. The kitchen comes with standard commercial appliances, like large refrigerators, stoves, and regular ole’ ovens — those are all of Excel’s standard features.

But what if you want to make wood-fired pizza? Can’t do that in a standard commercial baking oven. VBA is the pizza oven.

Pizza in a pizza oven

Yum.

Why use VBA in Excel?

Because wood-fired pizza is the best!

But seriously.

A lot of people spend a lot of time in Excel as a part of their jobs. Time in Excel moves differently, too. Depending on the circumstances, 10 minutes in Excel can feel like eternity if you’re not able to do what you need, or 10 hours can go by very quickly if everything is going great. Which is when you should ask yourself, why on earth am I spending 10 hours in Excel?

Sometimes, those days are inevitable. But if you’re spending 8-10 hours everyday in Excel doing repetitive tasks, repeating a lot of the same processes, trying to clean up after other users of the file, or even updating other files after changes are made to the Excel file, a VBA procedure just might be the solution for you.

You should consider using VBA if you need to:

  • Automate repetitive tasks
  • Create easy ways for users to interact with your spreadsheets
  • Manipulate large amounts of data

Getting Set Up to Write VBA in Excel

Developer Tab

To write VBA, you’ll need to add the Developer tab to the ribbon, so you’ll see the ribbon like this.

VBA developer tab

To add the Developer tab to the ribbon:

  1. On the File tab, go to Options > Customize Ribbon.
  2. Under Customize the Ribbon and under Main Tabs, select the Developer check box.

After you show the tab, the Developer tab stays visible, unless you clear the check box or have to reinstall Excel. For more information, see Microsoft help documentation.

VBA Editor

Navigate to the Developer Tab, and click the Visual Basic button. A new window will pop up — this is the Visual Basic Editor. For the purposes of this tutorial, you just need to be familiar with the Project Explorer pane and the Property Properties pane.

VBA editor

Excel VBA Examples

First, let’s create a file for us to play around in.

  1. Open a new Excel file
  2. Save it as a macro-enabled workbook (. xlsm)
  3. Select the Developer tab
  4. Open the VBA Editor

Let’s rock and roll with some easy examples to get you writing code in a spreadsheet using Visual Basic.

Example #1: Display a Message when Users Open the Excel Workbook

In the VBA Editor, select Insert -> New Module

Write this code in the Module window (don’t paste!):

Sub Auto_Open()
MsgBox («Welcome to the XYZ Workbook.»)
End Sub

Save, close the workbook, and reopen the workbook. This dialog should display.

Welcome to XYZ notebook message example

Ta da!

How is it doing that?

Depending on your familiarity with programming, you may have some guesses. It’s not particularly complex, but there’s quite a lot going on:

  • Sub (short for “Subroutine): remember from the beginning, “a group of VBA statements that performs one or more actions.”
  • Auto_Open: this is the specific subroutine. It automatically runs your code when the Excel file opens — this is the event that triggers the procedure. Auto_Open will only run when the workbook is opened manually; it will not run if the workbook is opened via code from another workbook (Workbook_Open will do that, learn more about the difference between the two).
  • By default, a subroutine’s access is public. This means any other module can use this subroutine. All examples in this tutorial will be public subroutines. If needed, you can declare subroutines as private. This may be needed in some situations. Learn more about subroutine access modifiers.
  • msgBox: this is a function — a group of VBA statements that performs one or more actions and returns a value. The returned value is the message “Welcome to the XYZ Workbook.”

In short, this is a simple subroutine that contains a function.

When could I use this?

Maybe you have a very important file that is accessed infrequently (say, once a quarter), but automatically updated daily by another VBA procedure. When it is accessed, it’s by many people in multiple departments, all across the company.

  • Problem: Most of the time when users access the file, they are confused about the purpose of this file (why it exists), how it is updated so often, who maintains it, and how they should interact with it. New hires always have tons of questions, and you have to field these questions over and over and over again.
  • Solution: create a user message that contains a concise answer to each of these frequently answered questions.

Real World Examples

  • Use the MsgBox function to display a message when there is any event: user closes an Excel workbook, user prints, a new sheet is added to the workbook, etc.
  • Use the MsgBox function to display a message when a user needs to fulfill a condition before closing an Excel workbook
  • Use the InputBox function to get information from the user

Example #2: Allow User to Execute another Procedure

In the VBA Editor, select Insert -> New Module

Write this code in the Module window (don’t paste!):

Sub UserReportQuery()
Dim UserInput As Long
Dim Answer As Integer
UserInput = vbYesNo
Answer = MsgBox(«Process the XYZ Report?», UserInput)
If Answer = vbYes Then ProcessReport
End Sub

Sub ProcessReport()
MsgBox («Thanks for processing the XYZ Report.»)
End Sub

Save and navigate back to the Developer tab of Excel and select the “Button” option. Click on a cell and assign the UserReportQuery macro to the button.

Now click the button. This message should display:

Process the XYZ report message example

Click “yes” or hit Enter.

Thanks for processing the XYZ report message example

Once again, tada!

Please note that the secondary subroutine, ProcessReport, could be anything. I’ll demonstrate more possibilities in example #3. But first…

How is it doing that?

This example builds on the previous example and has quite a few new elements. Let’s go over the new stuff:

  • Dim UserInput As Long: Dim is short for “dimension” and allows you to declare variable names. In this case, UserInput is the variable name and Long is the data type. In plain English, this line means “Here’s a variable called “UserInput”, and it’s a Long variable type.”
  • Dim Answer As Integer: declares another variable called “Answer,” with a data type of Integer. Learn more about data types here.
  • UserInput = vbYesNo: assigns a value to the variable. In this case, vbYesNo, which displays Yes and No buttons. There are many button types, learn more here.
  • Answer = MsgBox(“Process the XYZ Report?”, UserInput): assigns the value of the variable Answer to be a MsgBox function and the UserInput variable. Yes, a variable within a variable.
  • If Answer = vbYes Then ProcessReport: this is an “If statement,” a conditional statement, which allows us to say if x is true, then do y. In this case, if the user has selected “Yes,” then execute the ProcessReport subroutine.

When could I use this?

This could be used in many, many ways. The value and versatility of this functionality is more so defined by what the secondary subroutine does.

For example, maybe you have a file that is used to generate 3 different weekly reports. These reports are formatted in dramatically different ways.

  • Problem: Each time one of these reports needs to be generated, a user opens the file and changes formatting and charts; so on and so forth. This file is being edited extensively at least 3 times per week, and it takes at least 30 minutes each time it’s edited.
  • Solution: create 1 button per report type, which automatically reformats the necessary components of the reports and generates the necessary charts.

Real World Examples

  • Create a dialog box for user to automatically populate certain information across multiple sheets
  • Use the InputBox function to get information from the user, which is then populated across multiple sheets

Example #3: Add Numbers to a Range with a For-Next Loop

For loops are very useful if you need to perform repetitive tasks on a specific range of values — arrays or cell ranges. In plain English, a loop says “for each x, do y.”

In the VBA Editor, select Insert -> New Module

Write this code in the Module window (don’t paste!):

Sub LoopExample()
Dim X As Integer
For X = 1 To 100
Range(«A» & X).Value = X
Next X
End Sub

Save and navigate back to the Developer tab of Excel and select the Macros button. Run the LoopExample macro.

This should happen:

For-Next loop results

Etc, until the 100th row.

How is it doing that?

  • Dim X As Integer: declares the variable X as a data type of Integer.
  • For X = 1 To 100: this is the start of the For loop. Simply put, it tells the loop to keep repeating until X = 100. X is the counter. The loop will keep executing until X = 100, execute one last time, and then stop.
  • Range(«A» & X).Value = X: this declares the range of the loop and what to put in that range. Since X = 1 initially, the first cell will be A1, at which point the loop will put X into that cell.
  • Next X: this tells the loop to run again

When could I use this?

The For-Next loop is one of the most powerful functionalities of VBA; there are numerous potential use cases. This is a more complex example that would require multiple layers of logic, but it communicates the world of possibilities in For-Next loops.

Maybe you have a list of all products sold at your bakery in Column A, the type of product in Column B (cakes, donuts, or muffins), the cost of ingredients in Column C, and the market average cost of each product type in another sheet.

You need to figure out what should be the retail price of each product. You’re thinking it should be the cost of ingredients plus 20%, but also 1.2% under market average if possible. A For-Next loop would allow you to do this type of calculation.

Real World Examples

  • Use a loop with a nested if statement to add specific values to a separate array only if they meet certain conditions
  • Perform mathematical calculations on each value in a range, e.g. calculate additional charges and add them to the value
  • Loop through each character in a string and extract all numbers
  • Randomly select a number of values from an array

Conclusion

Now that we’ve talked about pizza and muffins and oh-yeah, how to write VBA code in Excel spreadsheets, let’s do a learning check. See if you can answer these questions.

  • What is VBA?
  • How do I get set up to start using VBA in Excel?
  • Why and when would you use VBA?
  • What are some problems I could solve with VBA?

If you have a fair idea of how to you could answer these questions, then this was successful.

Whether you’re an occasional user or a power user, I hope this tutorial provided useful information about what can be accomplished with just a bit of code in your Excel spreadsheets.

Happy coding!

7 Import Sheets: In this example, we will create a VBA macro that imports sheets from other Excel files into one Excel file.

8 Programming Charts: Use Excel VBA to create two programs. One program loops through all charts on a sheet and changes each chart to a pie chart. The other program changes some properties of the first chart.

9 CurrentRegion: You can use the CurrentRegion property in Excel VBA to return the range bounded by any combination of blank rows and blank columns.

10 Entire Rows and Columns: This example teaches you how to select entire rows and columns in Excel VBA. Are you ready?

11 Offset: The Offset property in Excel VBA takes the range which is a particular number of rows and columns away from a certain range.

12 From Active Cell to Last Entry: This example illustrates the End property of the Range object in Excel VBA. We will use this property to select the range from the Active Cell to the last entry in a column.

13 Background Colors: Changing background colors in Excel VBA is easy. Use the Interior property to return an Interior object. Then use the ColorIndex property of the Interior object to set the background color of a cell.

14 Compare Ranges: Learn how to create a program in Excel VBA that compares randomly selected ranges and highlights cells that are unique.

15 Option Explicit: We strongly recommend to use Option Explicit at the start of your Excel VBA code. Using Option Explicit forces you to declare all your variables.

Приветствую всех.

В этом посте я расскажу, что такое VBA и как с ним работать в Microsoft Excel 2007/2010 (для более старых версий изменяется лишь интерфейс — код, скорее всего, будет таким же) для автоматизации различной рутины.

VBA (Visual Basic for Applications) — это упрощенная версия Visual Basic, встроенная в множество продуктов линейки Microsoft Office. Она позволяет писать программы прямо в файле конкретного документа. Вам не требуется устанавливать различные IDE — всё, включая отладчик, уже есть в Excel.

Еще при помощи Visual Studio Tools for Office можно писать макросы на C# и также встраивать их. Спасибо, FireStorm.

Сразу скажу — писать на других языках (C++/Delphi/PHP) также возможно, но требуется научится читать, изменять и писать файлы офиса — встраивать в документы не получится. А интерфейсы Microsoft работают через COM. Чтобы вы поняли весь ужас, вот Hello World с использованием COM.

Поэтому, увы, будем учить Visual Basic.

Чуть-чуть подготовки и постановка задачи

Итак, поехали. Открываем Excel.

Для начала давайте добавим в Ribbon панель «Разработчик». В ней находятся кнопки, текстовые поля и пр. элементы для конструирования форм.

Появилась вкладка.

Теперь давайте подумаем, на каком примере мы будем изучать VBA. Недавно мне потребовалось красиво оформить прайс-лист, выглядевший, как таблица. Идём в гугл, набираем «прайс-лист» и качаем любой, который оформлен примерно так (не сочтите за рекламу, пожалуйста):

То есть требуется, чтобы было как минимум две группы, по которым можно объединить товары (в нашем случае это будут Тип и Производитель — в таком порядке). Для того, чтобы предложенный мною алгоритм работал корректно, отсортируйте товары так, чтобы товары из одной группы стояли подряд (сначала по Типу, потом по Производителю).

Результат, которого хотим добиться, выглядит примерно так:

Разумеется, если смотреть прайс только на компьютере, то можно добавить фильтры и будет гораздо удобнее искать нужный товар. Однако мы хотим научится кодить и задача вполне подходящая, не так ли?

Кодим

Для начала требуется создать кнопку, при нажатии на которую будет вызываться наша програма. Кнопки находятся в панели «Разработчик» и появляются по кнопке «Вставить». Вам нужен компонент формы «Кнопка». Нажали, поставили на любое место в листе. Далее, если не появилось окно назначения макроса, надо нажать правой кнопкой и выбрать пункт «Назначить макрос». Назовём его FormatPrice. Важно, чтобы перед именем макроса ничего не было — иначе он создастся в отдельном модуле, а не в пространстве имен книги. В этому случае вам будет недоступно быстрое обращение к выделенному листу. Нажимаем кнопку «Новый».

И вот мы в среде разработки VB. Также её можно вызвать из контекстного меню командой «Исходный текст»/«View code».

Перед вами окно с заглушкой процедуры. Можете его развернуть. Код должен выглядеть примерно так:

Sub FormatPrice()End Sub

Напишем Hello World:

Sub FormatPrice()
    MsgBox "Hello World!"
End Sub

И запустим либо щелкнув по кнопке (предварительно сняв с неё выделение), либо клавишей F5 прямо из редактора.

Тут, пожалуй, следует отвлечься на небольшой ликбез по поводу синтаксиса VB. Кто его знает — может смело пропустить этот раздел до конца. Основное отличие Visual Basic от Pascal/C/Java в том, что команды разделяются не ;, а переносом строки или двоеточием (:), если очень хочется написать несколько команд в одну строку. Чтобы понять основные правила синтаксиса, приведу абстрактный код.

Примеры синтаксиса

' Процедура. Ничего не возвращает

        foo "123""456" ' Скобки при вызове процедур запрещены

Грабли-1. При копировании кода из IDE (в английском Excel) есь текст конвертируется в 1252 Latin-1. Поэтому, если хотите сохранить русские комментарии — надо сохранить крокозябры как Latin-1, а потом открыть в 1251.

Грабли-2. Т.к. VB позволяет использовать необъявленные переменные, я всегда в начале кода (перед всеми процедурами) ставлю строчку Option Explicit. Эта директива запрещает интерпретатору заводить переменные самостоятельно.

Грабли-3. Глобальные переменные можно объявлять только до первой функции/процедуры. Локальные — в любом месте процедуры/функции.

Еще немного дополнительных функций, которые могут пригодится: InPos, Mid, Trim, LBound, UBound. Также ответы на все вопросы по поводу работы функций/их параметров можно получить в MSDN.

Надеюсь, что этого Вам хватит, чтобы не пугаться кода и самостоятельно написать какое-нибудь домашнее задание по информатике. По ходу поста я буду ненавязчиво знакомить Вас с новыми конструкциями.

Кодим много и под Excel

В этой части мы уже начнём кодить нечто, что умеет работать с нашими листами в Excel. Для начала создадим отдельный лист с именем result (лист с данными назовём data). Теперь, наверное, нужно этот лист очистить от того, что на нём есть. Также мы «выделим» лист с данными, чтобы каждый раз не писать длинное обращение к массиву с листами.

Sub FormatPrice()
    Sheets("result").Cells.Clear
    Sheets("data").Activate
End Sub

Работа с диапазонами ячеек

Вся работа в Excel VBA производится с диапазонами ячеек. Они создаются функцией Range и возвращают объект типа Range. У него есть всё необходимое для работы с данными и/или оформлением. Кстати сказать, свойство Cells листа — это тоже Range.

Примеры работы с Range

Sheets("result").Activate
Dim r As Range
Set r = Range("A1")
r.Value = "123"
Set r = Range("A3,A5")
r.Font.Color = vbRed
r.Value = "456"
Set r = Range("A6:A7")
r.Value = "=A1+A3"

Теперь давайте поймем алгоритм работы нашего кода. Итак, у каждой строчки листа data, начиная со второй, есть некоторые данные, которые нас не интересуют (ID, название и цена) и есть две вложенные группы, к которым она принадлежит (тип и производитель). Более того, эти строки отсортированы. Пока мы забудем про пропуски перед началом новой группы — так будет проще. Я предлагаю такой алгоритм:

  1. Считали группы из очередной строки.
  2. Пробегаемся по всем группам в порядке приоритета (вначале более крупные)
    1. Если текущая группа не совпадает, вызываем процедуру AddGroup(i, name), где i — номер группы (от номера текущей до максимума), name — её имя. Несколько вызовов необходимы, чтобы создать не только наш заголовок, но и всё более мелкие.
  3. После отрисовки всех необходимых заголовков делаем еще одну строку и заполняем её данными.

Для упрощения работы рекомендую определить следующие функции-сокращения:

Function GetCol(Col As IntegerAs String
    GetCol = Chr(Asc("A") + Col)
End FunctionFunction GetCellS(Sheet As String, Col As Integer, Row As IntegerAs Range
    Set GetCellS = Sheets(Sheet).Range(GetCol(Col) + CStr(Row))
End FunctionFunction GetCell(Col As Integer, Row As IntegerAs Range
    Set GetCell = Range(GetCol(Col) + CStr(Row))
End Function

Далее определим глобальную переменную «текущая строчка»: Dim CurRow As Integer. В начале процедуры её следует сделать равной единице. Еще нам потребуется переменная-«текущая строка в data», массив с именами групп текущей предыдущей строк. Потом можно написать цикл «пока первая ячейка в строке непуста».

Глобальные переменные

Option Explicit ' про эту строчку я уже рассказывал
Dim CurRow As Integer
Const GroupsCount As Integer = 2
Const DataCount As Integer = 3

FormatPrice

Sub FormatPrice()
    Dim I As Integer ' строка в data
    CurRow = 1
    Dim Groups(1 To GroupsCount) As String
    Dim PrGroups(1 To GroupsCount) As String

    Sheets(

"data").Activate
    I = 2
    Do While True
        If GetCell(0, I).Value = "" Then Exit Do
        ' ...
        I = I + 1
    Loop
End Sub

Теперь надо заполнить массив Groups:

На месте многоточия

Dim I2 As Integer
For I2 = 1 To GroupsCount
    Groups(I2) = GetCell(I2, I)
Next I2
' ...
For I2 = 1 To GroupsCount ' VB не умеет копировать массивы
    PrGroups(I2) = Groups(I2)
Next I2
I =  I + 1

И создать заголовки:

На месте многоточия в предыдущем куске

For I2 = 1 To GroupsCount
    If Groups(I2) <> PrGroups(I2) Then
        Dim I3 As Integer
        For I3 = I2 To GroupsCount
            AddHeader I3, Groups(I3)
        Next I3
        Exit For
    End If
Next I2

Не забудем про процедуру AddHeader:

Перед FormatPrice

Sub AddHeader(Ty As Integer, Name As String)
    GetCellS("result", 1, CurRow).Value = Name
    CurRow = CurRow + 1
End Sub

Теперь надо перенести всякую информацию в result

For I2 = 0 To DataCount - 1
    GetCellS("result", I2, CurRow).Value = GetCell(I2, I)
Next I2

Подогнать столбцы по ширине и выбрать лист result для показа результата

После цикла в конце FormatPrice

Sheets("Result").Activate
Columns.AutoFit

Всё. Можно любоваться первой версией.

Некрасиво, но похоже. Давайте разбираться с форматированием. Сначала изменим процедуру AddHeader:

Sub AddHeader(Ty As Integer, Name As String)
    Sheets("result").Range("A" + CStr(CurRow) + ":C" + CStr(CurRow)).Merge
    ' Чтобы не заводить переменную и не писать каждый раз длинный вызов
    ' можно воспользоваться блоком With
    With GetCellS("result", 0, CurRow)
        .Value = Name
        .Font.Italic = True
        .Font.Name = "Cambria"
        Select Case Ty
        Case 1 ' Тип
            .Font.Bold = True
            .Font.Size = 16
        Case 2 ' Производитель
            .Font.Size = 12
        End Select
        .HorizontalAlignment = xlCenter
    End With
    CurRow = CurRow + 1
End Sub

Уже лучше:

Осталось только сделать границы. Тут уже нам требуется работать со всеми объединёнными ячейками, иначе бордюр будет только у одной:

Поэтому чуть-чуть меняем код с добавлением стиля границ:

Sub AddHeader(Ty As Integer, Name As String)
    With Sheets("result").Range("A" + CStr(CurRow) + ":C" + CStr(CurRow))
        .Merge
        .Value = Name
        .Font.Italic = True
        .Font.Name = "Cambria"
        .HorizontalAlignment = xlCenterSelect Case Ty
        Case 1 ' Тип
            .Font.Bold = True
            .Font.Size = 16
            .Borders(xlTop).Weight = xlThick
        Case 2 ' Производитель
            .Font.Size = 12
            .Borders(xlTop).Weight = xlMedium
        End Select
        .Borders(xlBottom).Weight = xlMedium ' По убыванию: xlThick, xlMedium, xlThin, xlHairline
    End With
    CurRow = CurRow + 1
End Sub

Осталось лишь добится пропусков перед началом новой группы. Это легко:

В начале FormatPrice

Dim I As Integer ' строка в  data
CurRow = 0 ' чтобы не было пропуска в самом начале
Dim Groups(1 To GroupsCount) As String

В цикле расстановки заголовков

If Groups(I2) <> PrGroups(I2) Then
    CurRow = CurRow + 1
    Dim I3 As Integer

В точности то, что и хотели.

Надеюсь, что эта статья помогла вам немного освоится с программированием для Excel на VBA. Домашнее задание — добавить заголовки «ID, Название, Цена» в результат. Подсказка: CurRow = 0 CurRow = 1.

Файл можно скачать тут (min.us) или тут (Dropbox). Не забудьте разрешить исполнение макросов. Если кто-нибудь подскажет человеческих файлохостинг, залью туда.

Спасибо за внимание.

Буду рад конструктивной критике в комментариях.

UPD: Перезалил пример на Dropbox и min.us.

UPD2: На самом деле, при вызове процедуры с одним параметром скобки можно поставить. Либо использовать конструкцию Call Foo(«bar», 1, 2, 3) — тут скобки нужны постоянно.

Everybody in this country should learn how to program a computer... because it teaches you how to think." -Steve Jobs

I wish to extend the wise words of Steve Jobs and say everyone in the world should learn how to program a computer. You may not necessary end up working as a programmer or writing programs at all but it will teach you how to think.

In this VBA tutorial, we are going to cover the following topics.

  • What is Visual Basic for Applications (VBA)?
  • Why VBA?
  • Personal & Business Applications of VBA in Excel
  • Introduction to Visual Basic for Applications
  • Step by step example of creating a simple EMI calculator in Excel
  • How to use VBA in Excel Example

Visual Basic for Applications (VBA) is an event-driven programming language implemented by Microsoft to develop Office applications. VBA helps to develop automation processes, Windows API, and user-defined functions. It also enables you to manipulate the user interface features of the host applications.

Before we go into further details, let’s look at what computer programming is in a layman’s language. Assume you have a maid. If you want the maid to clean the house and do the laundry. You tell her what to do using let’s say English and she does the work for you. As you work with a computer, you will want to perform certain tasks. Just like you told the maid to do the house chores, you can also tell the computer to do the tasks for you.

The process of telling the computer what you want it to do for you is what is known as computer programming. Just as you used English to tell the maid what to do, you can also use English like statements to tell the computer what to do. The English like statements fall in the category of high level languages. VBA is a high level language that you can use to bend excel to your all powerful will.

VBA is actually a sub set of Visual Basic 6.0 BASIC stands for Beginners All-Purpose Symbolic Instruction Code.

Why VBA?

VBA enables you to use English like statements to write instructions for creating various applications. VBA is easy to learn, and it has easy to use User Interface in which you just have to drag and drop the interface controls. It also allows you to enhance Excel functionality by making it behave the way you want.

Personal & Business Applications of VBA in Excel

For personal use, you can use it for simple macros that will automate most of your routine tasks. Read the article on Macros for more information on how you can achieve this.

For business use, you can create complete powerful programs powered by excel and VBA. The advantage of this approach is you can leverage the powerful features of excel in your own custom programs.

Introduction to Visual Basic for Applications

Before we can write any code, we need to know the basics first. The following basics will help you get started.

  • Variable – in high school we learnt about algebra. Find (x + 2y) where x = 1 and y = 3. In this expression, x and y are variables. They can be assigned any numbers i.e. 1 and 3 respective as in this example. They can also be changed to say 4 and 2 respectively. Variables in short are memory locations. As you work with VBA Excel, you will be required to declare variables too just like in algebra classes
  • Rules for creating variables

    • Don’t use reserved words – if you work as a student, you cannot use the title lecturer or principal. These titles are reserved for the lecturers and the school authority. Reserved words are those words that have special meaning in Excel VBA and as such, you cannot use them as variable names.
    • Variable names cannot contain spaces – you cannot define a variable named first number. You can use firstNumber or first_number.
    • Use descriptive names – it’s very tempting to name a variable after yourself but avoid this. Use descriptive names i.e. quantity, price, subtotal etc. this will make your Excel VBA code easy to read
  • Arithmetic operators – The rules of Brackets of Division Multiplication Addition and Subtraction (BODMAS) apply so remember to apply them when working with expressions that use multiple different arithmetic operators. Just like in excel, you can use

    • + for addition
    • – for subtraction
    • * for multiplication
    • / for division.
  • Logical operators – The concept of logical operators covered in the earlier tutorials also apply when working with VBA. These include

    • If statements
    • OR
    • NOT
    • AND
    • TRUE
    • FALSE

How to Enable the Developer Tab

Below is the step by step process on how to enable the developer tab in Excel:

  • Create a new workbook
  • Click on the ribbon start button
  • Select options
  • Click on customize ribbon
  • Select the developer checkbox as shown in the image below
  • Click OK

Introduction to Macros in Excel

You will now be able to see the DEVELOPER tab in the ribbon

VBA Hello World!

Now we will demonstrate how to program in VBA programming language. All program in VBA has to start with “Sub” and end with “End sub”. Here the name is the name you want to assign to your program. While sub stands for a subroutine which we will learn in the later part of the tutorial.

Sub name()
.
.
. 
End Sub

We will create a basic VBA program that displays an input box to ask for the user’s name then display a greeting message

This tutorial assumes you have completed the tutorial on Macros in excel and have enabled the DEVELOPER tab in excel.

  • Create a new work book
  • Save it in an excel macro enabled worksheet format *.xlsm
  • Click on the DEVELOPER tab
  • Click on INSERT drop down box under controls ribbon bar
  • Select a command button as shown in the image below

Creating your First  Visual Basic for Applications (VBA) in Excel

Draw the command button anywhere on the worksheet

You will get the following dialogue window

Creating your First  Visual Basic for Applications (VBA) in Excel

  • Rename the macro name to btnHelloWorld_Click
  • Click on new button
  • You will get the following VBA code window

Creating your First  Visual Basic for Applications (VBA) in Excel

Enter the following instruction codes

Dim name As String
name = InputBox("Enter your name")
MsgBox "Hello " + name

HERE,

  • “Dim name as String” creates a variable called name. The variable will accept text, numeric and other characters because we defined it as a string
  • “name = InputBox(“Enter your name”)” calls the built in function InputBox that displays a window with the caption Enter your name. The entered name is then stored in the name variable.
  • MsgBox “Hello ” + name” calls the built in function MsgBox that display Hello and the entered name.

Your complete code window should now look as follows

Creating your First  Visual Basic for Applications (VBA) in Excel

  • Close the code window
  • Right click on button 1 and select edit text
  • Enter Say hello

Creating your First  Visual Basic for Applications (VBA) in Excel

  • Click on Say Hello
  • You will get the following input box

Creating your First  Visual Basic for Applications (VBA) in Excel

  • Enter your name i.e. Jordan
  • You will get the following message box

Creating your First  Visual Basic for Applications (VBA) in Excel

Congratulations, you just created your first VBA program in excel

Step by step example of creating a simple EMI calculator in Excel

In this tutorial exercise, we are going to create a simple program that calculates the EMI. EMI is the acronym for Equated Monthly Instalment. It’s the monthly amount that you repay when you get a loan. The following image shows the formula for calculating EMI.

Creating your First  Visual Basic for Applications (VBA) in Excel

The above formula is complex and can be written in excel. The good news is excel already took care of the above problem. You can use the PMT function to compute the above.

The PMT function works as follows

=PMT(rate,nper,pv)

HERE,

  • “rate” this is the monthly rate. It’s the interest rate divided by the number of payments per year
  • “nper” it is the total number of payments. It’s the loan term multiplied by number of payments per year
  • “pv” present value. It’s the actual loan amount

Create the GUI using excel cells as shown below

Creating your First  Visual Basic for Applications (VBA) in Excel

Add a command button between rows 7 and 8

Give the button macro name btnCalculateEMI_Click

Click on edit button

Enter the following code

Dim monthly_rate As Single, loan_amount As Double, number_of_periods As Single, emi As Double
monthly_rate = Range("B6").Value / Range("B5").Value
loan_amount = Range("B3").Value
number_of_periods = Range("B4").Value * Range("B5").Value 
emi = WorksheetFunction.Pmt(monthly_rate, number_of_periods, -loan_amount)
Range("B9").Value = emi

HERE,

  • “Dim monthly_rate As Single,…” Dim is the keyword that is used to define variables in VBA, monthly_rate is the variable name, Single is the data type that means the variable will accept number.
  • “monthly_rate = Range(“B6”).Value / Range(“B5″).Value” Range is the function used to access excel cells from VBA, Range(“B6”).Value makes reference to the value in B6
  • “WorksheetFunction.Pmt(…)” WorksheetFunction is the function used to access all the functions in excel

The following image shows the complete source code
