How to create, change, copy and delete VBA macros in Excel

This comprehensive guide empowers you to harness the potential of Excel macros. Learn to record macros, integrate VBA code, manage macros across workbooks, adjust settings, and much more. Even without VBA expertise, you can automate repetitive tasks.

For Excel beginners, macros might seem daunting. Mastering VBA takes time, but you can leverage macro automation immediately. This tutorial serves as your starting point, covering essential fundamentals and providing links to advanced resources.

What are Excel Macros?

An Excel macro is a sequence of instructions (VBA code) stored within a workbook. Essentially, it's a mini-program executing a predefined series of actions, reusable at any time. Macros primarily automate repetitive tasks, boosting efficiency. While often used interchangeably, a macro is the code itself, while VBA (Visual Basic for Applications) is the Microsoft programming language used to create them.

Why Use Excel Macros?

Macros significantly reduce workload. Imagine generating weekly reports involving data import, cleaning, formatting, charting, etc. A macro automates these steps, saving time and minimizing errors. While initial macro creation takes time, the long-term benefits are substantial.

Creating Excel Macros

Two methods exist: the Macro Recorder and the Visual Basic Editor (VBE).

1. Recording a Macro:

Even without programming knowledge, you can automate actions using the Macro Recorder. It tracks your keystrokes and mouse clicks, translating them into VBA code. The recorded code, while often verbose, is readily editable and reusable.

To begin recording: Click the "Record Macro" button (either on the Developer tab or the Status bar).

(See "How to record a macro in Excel" for detailed instructions.)

2. Writing a Macro in the VBE:

The VBE houses all macro code. Here, you can program complex actions, create functions, design dialog boxes, and implement logic. This requires VBA knowledge, but reusing existing code is straightforward.

To write a macro:

1. Open the VBE (Alt F11).
2. Insert a module (right-click the project, select "Insert" > "Module").
3. Paste your VBA code.
4. Run the macro (F5).

(See "How to insert VBA code in Excel" for detailed steps.)

Running, Enabling, and Managing Macros

Running Macros:

• From a worksheet: Click "Macros" (Developer tab) or use Alt F8.
• From the VBE: Press F5 (run all) or F8 (step-through debugging).
• Custom buttons or shortcuts can also trigger macros. (See "How to run macros in Excel" for details.)

Enabling Macros:

Macros are disabled by default for security. Click "Enable Content" in the security warning bar when opening a macro-enabled workbook. (See "How to enable and disable macros in Excel" for more.)

Macro Settings:

Excel's macro security is controlled in the Trust Center. Access it via File > Options > Trust Center > Trust Center Settings… > Macro Settings. (See "Excel macro settings explained" for details.)

Viewing, Editing, and Debugging VBA Code

The VBE is used to view, edit, and debug macros. Open it via Alt F11 or the "Visual Basic" button (Developer tab). F8 allows step-by-step code execution for debugging.

Copying Macros

Copy an entire module (drag-and-drop in the VBE) or just the code of a specific macro (copy-paste).

Deleting Macros

Delete macros via the "Macros" dialog box (Alt F8) or directly in the VBE (delete the code or remove the entire module).

Saving, Exporting, and Importing Macros

Save macro-enabled workbooks as .xlsm files. Export modules as .bas files for sharing or transferring. Import *.bas files into other workbooks via the VBE's "Import File" option.

Macro Examples

Simple examples illustrate basic VBA functionalities: unhiding sheets, hiding the active sheet, unmerging cells, and displaying message boxes. Links to more complex examples are provided.

Protecting Macros

Lock projects for viewing (VBAProject Properties) to prevent code viewing and editing. Password-protect macro execution using Application.InputBox for added security. (Note: This is not foolproof.)

Macro Tips

Improve macro speed by disabling screen updating and calculation during execution. Break long code lines using the underscore (_) as a line continuation character. Store macros in the Personal Macro Workbook for universal access. Save the workbook before macro execution to allow easy undo. Remove empty modules to prevent unnecessary security warnings.
