VBA (Visual Basic for Applications) is a programming language developed by Microsoft that is primarily used for automating tasks and creating custom applications within Microsoft Office programs like Excel, Word, and Access. VBA allows users to write macros—sets of instructions that automate repetitive tasks, such as data processing, report generation, and complex calculations. It provides an easy-to-learn syntax and is widely used in business, finance, and data analysis for increasing productivity and creating customized solutions within the Microsoft Office suite.
