How I Learned Excel in My First Week Of Data Science - Real-World Uses Explained

When I started learning Data Science, I expected to spend my first week writing Python code, exploring machine learning models, and working with advanced tools. Instead, I spent most of my time in Excel. At first, it felt underwhelming—just rows, columns, and simple spreadsheets. But within a few days, I realized something important: Excel is not a basic tool at all.
