VBA is a scripting language for controlling Microsoft programs
VBA stands for Visual Basic for Applications and is a scripting language that controls the processes of Microsoft Office programs like Word, Excel, Access and Outlook, and lets them be easily organised.
VBA is useful for creating tables in Excel: work steps that are repetitive can be programmed as macros and called up at any time. This not only facilitates the work, but also minimises the error rate. VBA users can program new worksheet functions in Excel with the scripting language: no Excel user will need to struggle anymore with long, almost incomprehensible formulas. With a self-composed function everyone is able to use the built-in expertise. Saved as an add-in, the new functions can then be easily used on all workstations; the add-in distribution is done by email.
VBA facilitates the processes in various programs
You can also create complex applications with VBA: whether you need a marketing database or a reporting tool. The application is more convenient, safer and easier to use with VBA. In addition, VBA creates a kind of control panel, i.e. other Office applications can be quasi remotely controlled. For example, numbers from single cells in an Excel can be read, checked and then placed in an Access table or distributed into a Word document.
By using the self-programmed document assistant through VBA, you can easily create a new Word document. For example, the document is filled automatically with names, telephone numbers and email addresses of the users registered with the operating system, automatic corrections of the margins for the printer can be made or databases can be connected.
