Tracy Syrstad has been deeply immersed in the world of Excel programming for 20 years, acquiring a comprehensive skillset largely through independent learning. VBA is more than just a programming language for her; it's a tool to unlock efficiency. Tracy's passion for empowering clients through automated projects and one-on-one Excel programming instruction extends beyond personal development. This hands-on experience, combined with her proven track record of authoring seven previous VBA books for Microsoft Press, equips her with the unique ability to translate complex Excel concepts into clear and engaging content for a broad audience.
