With Visual Basic for Applications (VBA), you can transform Excel into a task-specific piece of software that will quickly and precisely serve your needs. This single-source reference and how-to guide will teach you to use the complete range of Excel programming tasks to solve problems. Developers looking forward to .NET development will also find discussion of how the Excel object model works with .NET tools, including Visual Studio Tools for Office (VSTO).
Why program Excel? For solving complex calculations and presenting results, Excel is amazingly complete with every imaginable feature already in place. But programming Excel isn't about adding new features as much as it's about combining existing features to solve particular problems. With a few modifications, you can transform Excel into a task-specific piece of software that will quickly and precisely serve your needs. In other words, Excel is an ideal platform for probably millions of small spreadsheet-based software solutions.
