Microsoft Office is an integrated suite of applications that includes Outlook, Word, Excel, Access, PowerPoint, Visio and InfoPath, along with a number of tools to assist in making the individual components work together. Coding within and between the projects is done in Visual Basic for Applications, known as VBA.

VBScript (Visual Basic Scripting Edition) is an interpreted scripting language developed by Microsoft that is modeled on Visual Basic, but with some important differences. VBScript is commonly used for automating administrative and other tasks in Windows operating systems (by means of the Windows Script Host) and for server-side scripting in ASP web applications. It is also used for client-side scripting in Internet Explorer, specifically in intranet web applications.

Visual Basic for Applications (VBA) enables building user-defined functions (UDFs), automating processes and accessing Windows API and other low-level functionality through dynamic-link libraries (DLLs). VBA is closely related to Visual Basic and uses the Visual Basic Runtime Library, but it can normally only run code within a host application rather than as a standalone program. It can, however, be used to control one application from another via OLE Automation. VBA is built into most Microsoft Office applications.

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.

Microsoft applications include a variety of software programs, including development and digital authoring programs (Expression and Media Center), educational programs, Internet software, including Essentials, Skype and the Live family, anti-virus, productivity applications and suites like Office, Excel, Word, Outlook, Access and PowerPoint, video games and server applications such as Exchange, SharePoint, IIS and Virtual Server.
