Excel allows users to work with rows and columns of data, perform complex calculations, create charts and graphs, and even automate repetitive tasks with macros.

2. Key Features of Microsoft Excel

a) Spreadsheet Structure

Excel uses a grid system consisting of rows (numbered 1, 2, 3…) and columns (labeled A, B, C…), creating individual cells.
Each cell can contain text, numbers, dates, or formulas.
Cells are referenced using their column and row identifier, e.g., A1, B2.

Example functions:
- SUM() – adds numbers.
- AVERAGE() – calculates the average.

Users can also create custom formulas for specific calculations.

c) Data Visualization

Excel allows creation of charts and graphs, such as:
- Column, bar, line, and pie charts
- Scatter plots
- Area charts and histograms
Conditional formatting lets users highlight important data, e.g., values above a certain threshold.
