Running macros in Excel - Deep Dive

Overview - Running macros

What is it?

Running macros means telling Excel to perform a set of recorded or written instructions automatically. These instructions, called macros, help you do repetitive tasks quickly without clicking many buttons. You can run macros by clicking buttons, using keyboard shortcuts, or from the Excel menu. This saves time and reduces mistakes in your work.

Why it matters

Without macros, you would have to do repetitive tasks manually, which takes a lot of time and can lead to errors. Running macros automates these tasks, making your work faster and more reliable. This is especially helpful when working with large data sets or complex formatting. It lets you focus on important decisions instead of routine work.

Where it fits

Before learning to run macros, you should know basic Excel skills like entering data and using simple formulas. After mastering running macros, you can learn how to write your own macros using VBA (Visual Basic for Applications) to create custom automation.

Mental Model

Core Idea

Running a macro is like pressing a play button that makes Excel repeat a saved set of steps automatically.

Think of it like...

Imagine you have a coffee machine with a button that makes your favorite coffee exactly how you like it. Running a macro is like pressing that button to get the same coffee every time without doing each step yourself.

What is a macro in Excel

Concept: Introduce the idea of macros as recorded actions in Excel.

A macro is a saved set of instructions that tells Excel to do tasks automatically. You can record a macro by clicking the 'Record Macro' button, then doing the steps you want Excel to remember. When you stop recording, Excel saves these steps as a macro.

Result

You have a macro that can repeat your recorded steps anytime you run it.

Understanding macros as recorded actions helps you see how Excel can automate repetitive tasks without writing code.

How to run a macro manually

Concept: Teach the basic ways to run a macro in Excel.

To run a macro, go to the 'View' tab, click 'Macros', then select the macro name and click 'Run'. Alternatively, you can assign a macro to a button or use a keyboard shortcut if set up.

Result

Excel performs the recorded steps automatically when you run the macro.

Knowing how to run macros manually is the first step to using automation effectively.

Running macros with keyboard shortcuts

🤔Before reading on: do you think you can run any macro with a keyboard shortcut by default? Commit to yes or no.

Concept: Explain how to assign and use keyboard shortcuts to run macros quickly.

When recording or editing a macro, you can assign a keyboard shortcut like Ctrl+Shift+M. Pressing this shortcut runs the macro immediately without opening menus. This speeds up your workflow.

Result

You can run your macro instantly by pressing the assigned keys.

Using keyboard shortcuts for macros saves time and makes automation feel seamless.

Intermediate

Running macros from buttons on sheets

🤔Before reading on: do you think you can add a button on your sheet that runs a macro? Commit to yes or no.

Concept: Show how to add clickable buttons on Excel sheets to run macros easily.

You can insert a button from the Developer tab, then assign a macro to it. Clicking the button runs the macro. This is useful for users who prefer clicking over keyboard shortcuts.

Result

A button appears on the sheet that runs the macro when clicked.

Buttons make macros accessible to anyone using the sheet, improving usability.

5

Intermediate

Running macros with the Quick Access Toolbar

Concept: Explain how to add macros to the Quick Access Toolbar for easy access.

You can customize the Quick Access Toolbar by adding your macro. Click the dropdown arrow on the toolbar, choose 'More Commands', select your macro, and add it. Now the macro runs with one click from the toolbar.

Result

Macro runs quickly from the toolbar without navigating menus.

Adding macros to the toolbar integrates automation into your daily Excel workflow.

6

Advanced

Running macros automatically on events

🤔Before reading on: do you think macros can run automatically when you open a file or change a cell? Commit to yes or no.

Concept: Introduce event-driven macros that run automatically based on triggers.

You can write VBA code to run macros automatically when events happen, like opening a workbook or changing a cell. This uses special event procedures like Workbook_Open or Worksheet_Change. It automates tasks without user action.

Result

Macros run by themselves when specific events occur in Excel.

Event-driven macros enable powerful automation that reacts to your work without manual running.

7

Expert

Security and permissions when running macros

🤔Before reading on: do you think all macros run freely without restrictions? Commit to yes or no.

Concept: Explain macro security settings and how Excel protects users from harmful macros.

Excel has security settings that can block macros from running if they come from unknown sources. You can adjust settings to enable or disable macros. Trusted locations and digital signatures help manage safe macro use. Understanding this prevents security risks.

Result

Macros run only when allowed, protecting your computer from malicious code.

Knowing macro security helps you safely use automation without risking harmful code.

Under the Hood

When you run a macro, Excel reads the stored VBA code or recorded steps and executes them one by one. The macro commands interact with Excel's objects like cells, sheets, and workbooks to perform actions. Excel's VBA engine interprets the code and controls the application accordingly.

Why designed this way?

Macros were designed to automate repetitive tasks without requiring users to write code. Recording actions made automation accessible to beginners. The VBA language was added to allow advanced users to customize and extend functionality. Security controls were introduced to protect users from malicious macros.

Myth Busters - 4 Common Misconceptions

Quick: do you think running a macro always requires opening the VBA editor? Commit to yes or no.

Common Belief: You must open the VBA editor to run any macro.

Reality: You can run macros directly from Excel menus, buttons, or shortcuts without opening the VBA editor.

Why it matters: Believing this slows down users and discourages them from using macros effectively.

Quick: do you think macros run automatically as soon as you open any Excel file? Commit to yes or no.

Common Belief: Macros always run automatically when opening a file.

Reality: Macros only run automatically if specifically programmed to do so with event procedures and if security settings allow it.

Why it matters: Assuming all macros run automatically can cause confusion and security concerns.

Quick: do you think all macros are safe to run from any source? Commit to yes or no.

Common Belief: All macros are safe and can be run without worry.

Reality: Macros can contain harmful code; Excel's security settings help protect users by disabling or warning about unsafe macros.

Why it matters: Ignoring macro security risks can lead to malware infections or data loss.

Quick: do you think running a macro changes your original data permanently without undo? Commit to yes or no.

Common Belief: You can always undo changes made by running a macro.

Reality: Running a macro often cannot be undone with the Undo button, so changes are permanent unless you saved a backup.

Why it matters: Expecting undo can cause accidental data loss if macros modify data unexpectedly.

Expert Zone

1

Macros can be paused or stepped through in the VBA editor for debugging, which helps find errors in complex automation.

2

Assigning macros to shapes or images on sheets can create intuitive user interfaces beyond simple buttons.

3

Event-driven macros can slow down Excel if not carefully written, so efficient coding and disabling events during macro runs is important.

When NOT to use

Avoid using macros when sharing files with users who have macro security disabled or use non-Windows Excel versions that do not support VBA well. Instead, use built-in Excel functions, Power Query, or Office Scripts for safer automation.

Production Patterns

Professionals use macros to automate report generation, data cleaning, and formatting tasks. They often combine macros with user forms for input and error handling. In large organizations, macros are stored in add-ins for reuse and version control.

Connections

Event-driven programming

Running macros on events builds on event-driven programming concepts.

Understanding event-driven programming helps grasp how macros can react automatically to user actions or data changes.

Automation in software testing

Both use scripts to automate repetitive tasks to save time and reduce errors.

Knowing macro automation parallels software testing automation reveals shared goals of efficiency and reliability.

Assembly line in manufacturing

Running macros is like an assembly line automating repeated steps to produce consistent results.

Seeing macros as an assembly line clarifies how automation improves speed and quality in work processes.

Common Pitfalls

#1 Trying to run a macro without enabling macros in Excel security settings.

Wrong approach:

Open Excel file and try to run macro without changing security settings; macro does not run.

Correct approach:

Go to File > Options > Trust Center > Trust Center Settings > Macro Settings, then enable macros or trust the document location.

Root cause:

Excel disables macros by default to protect users, so they must be enabled before running.

#2 Assigning a macro to a button but forgetting to link the macro name.

Wrong approach:

Insert button and click it, but no macro runs because none was assigned.

Correct approach:

Right-click button, choose 'Assign Macro', then select the macro to link it.

Root cause:

Buttons do not run macros automatically; they must be explicitly connected.

#3 Running a macro that changes data expecting to undo changes with Ctrl+Z.

Wrong approach:

Run macro, then press Undo expecting to revert changes; nothing happens.

Correct approach:

Save a backup before running macros or design macros to save previous states if undo is needed.

Root cause:

Excel's Undo does not track macro actions, so changes are permanent unless handled.

Key Takeaways

Running macros automates repetitive Excel tasks by executing saved instructions quickly and accurately.

You can run macros manually from menus, buttons, keyboard shortcuts, or automatically on events.

Macro security settings protect you from harmful code but require enabling trusted macros to run.

Macros often cannot be undone, so always save your work before running them.

Advanced use includes event-driven macros and integrating macros into user-friendly interfaces.
