What is VBA?
Visual Basic for Applications (VBA) is a programming language primarily found in Microsoft Office products (Excel, Word, PowerPoint, Access etc.), and serves mainly as a tool for automating workflows. It helps take repetitive and sometimes complicated tasks prone to human error, and executes them for you. A well thought out VBA script can not only save you a lot of time but can also drastically improve the accuracy for your work.
