Introduction

      In its broadest sense, a macro is a sequence of instructions that automates some aspect of Excel so that you can work more efficiently and with fewer errors. You might create a macro, for example, to format and print a month-end sales report. After you develop the macro, you can execute it to perform many time-consuming procedures automatically.

      Macros are written in VBA, which stands for Visual Basic for Applications. VBA is a programming language developed by Microsoft and a tool used to develop programs that control Excel.

      Excel programming terminology can be a bit confusing. For example, VBA is a programming language but also serves as a macro language. What do you call something written in VBA and executed in Excel? Is it a macro or is it a program? Excel’s Help system often refers to VBA procedures as macros, so this is the terminology used in this book.

      You also see the term automate throughout this book. This word means that a series of steps are completed automatically. For example, if you write a macro that adds color to some cells, prints the worksheet, and then removes the color, you have automated those three steps.

      You’re probably aware that people use Excel for thousands of different tasks. Here are just a few examples:

The list could go on and on. The point is simply that Excel is used for a wide variety of tasks, and everyone reading this book has different needs and expectations regarding Excel. One thing most readers have in common, however, is the need to automate some aspect of Excel, which is what macros (and this book) are all about.

About This Book

      This book approaches the topic of Excel macros with the recognition that programming VBA takes time and practice — time that you may not have right now. In fact, many analysts don’t have the luxury of taking a few weeks to become expert at VBA. So instead of the same general overview of VBA topics, this book provides some of the most commonly used real-world Excel macros.

      Each section in the book outlines a common problem and provides an Excel macro to solve the problem — along with a detailed explanation of how the macro works and where to use it.

      Each section presents the following:
