This 5-day long class is for anyone who is new to Excel or has used it and felt relieved when it worked. Excel is powerful, but completely literal — it doesn’t interpret or think. It simply follows the structure you give it, which is why charts show blank labels, sorts break rows apart, or numbers refuse to calculate. These aren’t Excel failures; they’re Excel obeying rules most users have never been taught. In this session, you’ll learn how Excel actually works: how it reads your data, how structure affects results, and how to avoid the common problems that make the program feel unpredictable. You’ll also practice essential tasks such as entering clean data, building reliable formulas, organizing information, and creating charts that update correctly.
