A Macros developer creates automated tasks, known as macros, primarily in software like Microsoft Excel or Access. They use a specific scripting language, like Visual Basic for Applications (VBA), to write code that automates repetitive tasks, enhances UI, or integrates different software. They also test and debug these macros, ensuring they function correctly and efficiently. They often analyze business processes to identify areas where automation could increase efficiency and accuracy. Their role may also involve training users on how to use these macros and providing ongoing support and updates as needed.
