Excel is a powerful tool for performing calculations, creating graphics, and analyzing data. It allows users to enter data into cells organized in a spreadsheet. Different types of charts can be created in Excel to visualize data, such as funnel charts, pie charts, column charts, area charts, line charts, map charts, scatter plots, bar charts, and histograms. Formulas and pivot tables allow users to calculate and sort data in useful ways. Conditional formatting brings out patterns in data by formatting cells based on their values.
