Excel Introduction
Microsoft Excel is a powerful spreadsheet program that helps users organize, analyze, and visualize data. It is widely used in business, education, and daily personal tasks. Excel provides tools like formulas, functions, charts, and pivot tables to perform data manipulation and analysis efficiently.

Understanding Excel Layout
When you open Excel, you are presented with a workbook consisting of sheets. Each sheet contains cells organized in rows and columns. The interface includes the ribbon (menu bar), formula bar, and sheet tabs.
Ribbon: Contains tabs like Home, Insert, Page Layout, Formulas, Data, Review, and View.
Formula Bar: Displays the contents or formula in the selected cell.
Cell: The basic unit in Excel, identified by its address (e.g., A1).
Basic Operations in Excel
Excel allows you to enter and format data, apply filters, sort data, and perform calculations.
Entering Data: Click a cell and type. Press Enter to move down, or Tab to move right.
Formatting: Use the Home tab to apply styles, font changes, number formats, etc.
Sorting & Filtering: Use the Data tab to sort columns or apply filters to lists.
Formulas and Functions
Formulas in Excel always start with an equal sign (=). Functions are predefined formulas like SUM, AVERAGE, etc.
Example 1: =B2*C2 — Multiplies Quantity by Unit Price (useful in sales calculations)
Example 2: =SUM(D2:D6) — Adds all values in the Total column (e.g., Total Sales)
Example 3: =AVERAGE(E2:E6) — Finds average profit
Sample Dataset (Excel-style View)
Below is a demo dataset styled like Excel, with column letters and row numbers to visualize how cell references work.
| A | B | C | D | E | |
|---|---|---|---|---|---|
| 1 | Product | Quantity | Unit Price | Total | Profit |
| 2 | Pen | 10 | 5 | =B2*C2 | 10 |
| 3 | Notebook | 20 | 15 | =B3*C3 | 30 |
| 4 | Bag | 5 | 200 | =B4*C4 | 80 |
| 5 | Marker | 12 | 7 | =B5*C5 | 15 |
| 6 | Scale | 18 | 3 | =B6*C6 | 5 |
Note: Columns D and E use formulas. For example, D2 = B2 * C2, and similarly for others. Column E (Profit) values can be static or formula-based (e.g., D2 - cost).
Key Takeaways
- Excel is used to manage, calculate, and visualize structured data.
- Each Excel file is called a workbook, made up of multiple sheets.
- Formulas and functions provide dynamic calculations.
- Commonly used functions include SUM, AVERAGE, MIN, MAX, COUNT, etc.
- Sorting, filtering, and formatting tools help present data effectively.
- Real-world datasets help demonstrate cell references, formulas, and function usage.
