. Pivot tables -its easier to manage big dataset using pivot tables. A good example Jumia dataset.
Data Analysis
Excel is a powerful tool for analyzing datasets. It allows users to clean data, identify patterns, and draw meaningful insights that support decision-making.
Key Excel Features and Formulas
Pivot Tables
Pivot tables are one of Excel’s most powerful features. They allow users to summarize large datasets quickly. For example, a pivot table can show total sales by product or region without manually calculating each value.
