Microsoft Excel is widely used for organising data, performing calculations, preparing reports and analysing business information. However, many Excel tasks involve repeating the same steps every day or every month. This is where Excel macros become useful.
An Excel macro is a recorded sequence of actions or a set of VBA instructions that automates repetitive tasks in a worksheet. Instead of manually formatting data, applying calculations or preparing reports every time, you can run a macro to perform those actions automatically.
For example, if you regularly prepare monthly sales reports, you can create a macro to format headings, apply borders, adjust column widths and highlight important figures with a single command.
Whether you are a student learning Excel, a business analyst handling reports or a professional preparing for data analyst interviews, understanding macros can help you work more efficiently.
In this guide, you will learn what Excel macros are, how to create and record them, how to use VBA code, and how to apply macros to practical tasks.
A macro in Excel is a tool that automates a sequence of actions. It records the steps you perform in a worksheet or uses VBA (Visual Basic for Applications) code to complete a task automatically.
Once created, a macro can be run whenever you need to repeat the same process. You can execute it from the Developer tab, assign it a keyboard shortcut or connect it to a button in your worksheet.
Example: Imagine that you receive a sales report every month. You need to make the headings bold, add background colours, apply borders and adjust column widths. Instead of repeating these steps manually, you can record them in a macro and run it whenever a new report arrives.
Excel is an important tool for data analysis across industries such as finance, marketing, healthcare, retail and operations. Analysts use it to organise datasets, identify patterns, perform calculations and prepare reports.
However, working with large datasets often involves repetitive activities. For example, an analyst may need to clean data, remove unnecessary formatting, calculate totals or prepare monthly performance reports.
Excel macros help automate these routine activities, allowing professionals to spend more time interpreting data and generating insights.
Here are some important benefits of using macros in data analysis:

Excel macros can be created in different ways depending on the complexity of the task and the user's technical knowledge.
The two common approaches are:
A recorded macro captures the actions you perform in Excel and converts them into VBA instructions.
You do not need to write code manually. Simply start recording, perform the required actions and stop recording. Excel saves those steps as a macro that you can run again.
Example: Recording the steps required to format a sales report, including bold headings, cell borders and column adjustments.
VBA macros are created or edited using Visual Basic for Applications, the programming language used by Excel for desktop automation.
Unlike recorded macros, VBA macros allow users to write custom instructions, apply conditions, create loops and automate more complex tasks.
Example: Writing VBA code to identify blank cells in a dataset, highlight missing values or calculate totals across multiple worksheets.
VBA stands for Visual Basic for Applications. It is a programming language used to automate tasks and customise applications such as Microsoft Excel.
Excel uses VBA to create and run macros. Users can write VBA instructions directly in the Visual Basic Editor or modify the code generated by the Macro Recorder.
For example, the following VBA code displays a message when the macro runs:
Sub MyFirstMacro()
MsgBox "Welcome to Excel Macros!"
End Sub
When you run this macro, Excel displays a message box containing the text.
VBA is particularly useful when you want to automate tasks that require more than a simple sequence of recorded actions.
Excel macros can be used for several business and data-management activities. Here are some common examples:
Suppose you receive a spreadsheet every week and need to apply the same formatting to its headings and columns.
A macro can automatically:
This helps maintain a consistent format across reports.
Large datasets may contain blank rows, inconsistent formatting or duplicate information.
Macros can automate specific data-cleaning steps, such as:
Always review the dataset and test the macro on a copy before applying changes to important information.
Finance and business teams often prepare reports using the same format every month.
A macro can automate repetitive steps such as calculating totals, formatting tables, highlighting important figures and preparing summary sections.
If you regularly calculate commissions, sales totals or departmental expenses, a macro can automate the required calculations and apply them to the relevant cells.
VBA can automate activities across multiple worksheets within a workbook. For example, a macro can collect selected information from different department sheets and compile it into a summary sheet.
Before creating or recording a macro, you need to enable the Developer tab. It contains tools for recording macros, opening the VBA Editor and managing macro settings.
Follow these steps in Excel for Windows:
The Developer tab will now appear on the Excel ribbon.
Note: The steps may differ slightly depending on your Excel version and operating system.
You can create a simple macro using Excel's built-in Macro Recorder. For beginners, this is one of the easiest ways to understand how automation works.
Let's create a macro that formats a sales report.
Open the Excel workbook containing the data you want to format. For this example, assume your sales report contains columns for product name, quantity, price and total sales.
Click the Developer tab on the Excel ribbon. In the Code section, select Record Macro.
A Record Macro dialogue box will appear. Enter the following details:
Click OK to start recording.
Now perform the actions you want Excel to record. For this example:
Excel will record the actions as you perform them.
Once you have completed the formatting, return to the Developer tab and click Stop Recording.
Your macro has now been created.
To test your macro, go to Developer > Macros, select FormatSalesReport and click Run.
Excel will execute the recorded steps.
Recording a macro is useful when you want Excel to capture a series of actions without writing VBA code.
Follow this quick process:
Tip: Use descriptive macro names so that you can identify their purpose later. For example, use FormatMonthlyReport instead of a generic name such as Macro1.
You can also use the Use Relative References option on the Developer tab when you want recorded actions to work relative to the currently selected cell rather than always referring to the same fixed cell addresses.
Once you have created a macro, you can run it whenever you need to repeat the automated task.
Here are the common ways to execute a macro:
Excel will perform the actions saved in that macro.
If you assigned a shortcut key while creating the macro, you can use that shortcut to run it.
For example, if you assigned a shortcut to your report-formatting macro, pressing that key combination will execute the recorded steps.
You can also assign a macro to a button in your worksheet.
You can change the button's displayed text to something meaningful, such as Format Report. Clicking it will run the assigned macro.
If you want to automate more complex activities, you can write VBA code directly instead of relying only on the Macro Recorder.
Let's understand how to create a simple VBA macro that formats a sales report.
Suppose your sales data is stored in columns A to D, with the headings in the first row.
You can use the following VBA code to make the headings bold, apply a background colour, add borders and automatically adjust column widths.
Sub FormatSalesReport()
With Range("A1:D1")
.Font.Bold = True
.Interior.Color = RGB(217, 225, 242)
End With
Range("A1:D10").Borders.LineStyle = xlContinuous
Columns("A:D").AutoFit
End Sub
How this code works:
Note: This example is designed for a report with headings in row 1 and data in rows 1 to 10. Adjust the ranges to match your worksheet.
If you want to retain your macros after closing Excel, you must save the workbook in a format that supports VBA.
The standard .xlsx format does not store VBA macro code. Instead, use the Excel Macro-Enabled Workbook (.xlsm) format.
Follow these steps:
Your workbook will now retain its VBA macros.
If you want to make a macro available whenever you open Excel on your computer, you can store it in the Personal Macro Workbook (PERSONAL.XLSB).
Excel uses security settings to control whether macros can run. This is important because VBA macros can contain malicious code.
By default, Excel commonly uses a setting that disables macros with a notification, allowing users to decide whether to trust a particular file.
To review your macro settings in Excel for Windows:
Important: Avoid selecting "Enable all macros" as a general setting. Microsoft identifies this option as potentially dangerous because it can allow malicious code to run. Only run macros from sources you trust, and follow your organisation's IT security policies.
Files downloaded from the internet may also have their macros blocked by Office security features. Do not bypass these protections unless you have verified the file and its source.
After creating macros, you may need to review their code, make changes or remove macros that are no longer required.
To edit a macro, open it in the Visual Basic Editor and modify the relevant VBA instructions.
After making changes, save the workbook and test the macro using a copy of your data. This helps ensure that the updated code works as expected.
If the macro is stored in a different workbook or in the Personal Macro Workbook, make sure you select the correct location before removing it.
Excel offers more than one way to automate spreadsheet tasks. VBA macros and Office Scripts are two important options, but they are not the same technology.

Here are some common questions you may encounter:
A macro is a recorded sequence of actions or a set of VBA instructions that automates repetitive tasks in Excel. It helps save time, improve consistency and reduce manual work.
VBA stands for Visual Basic for Applications. It is the programming language used to create and customise macros in desktop Excel.
A recorded macro captures actions performed by a user in Excel and generates VBA code. A VBA macro is created or modified by writing code directly, allowing more complex automation.
A workbook containing VBA macros should generally be saved in the .xlsm format, also known as an Excel Macro-Enabled Workbook.
A macro can automate data-cleaning activities such as removing blank rows, highlighting missing values, standardising text and identifying duplicate entries. The exact steps depend on the dataset and the required cleaning rules.
First, check whether the workbook is saved in a macro-enabled format and whether its security settings allow the macro to run. Then open the VBA Editor, review the code and use debugging tools such as breakpoints and step-by-step execution to identify errors.
VBA macros use Visual Basic for Applications and are designed primarily for desktop Excel automation. Office Scripts use TypeScript and support cloud-based automation across supported Excel environments.
