2️⃣ Understanding the Excel Interface

When you open Excel, you see:

Workbook

A file in Excel is called a workbook.

Worksheet

Each workbook contains sheets (like pages in a notebook).

Rows and Columns

• Rows → Horizontal (1, 2, 3, …)
• Columns → Vertical (A, B, C, …)

Cells

A cell is where a row and column meet.

Example:

• A1 → Column A, Row 1
• B2 → Column B, Row 2

3️⃣ Example of a Simple Excel Table

Below is an example of what a small Excel sheet might look like (in markdown format):

| Name    | Age | Score |
|---------|-----|-------|
| Alice   | 23  | 85    |
| Bob     | 25  | 90    |
| Charlie | 22  | 78    |

In Excel:

• "Name" might be in cell A1
• "Age" in B1
• "Score" in C1

4️⃣ Basic Excel Formulas

Formulas always start with:

=

Let’s look at common beginner formulas.

SUM (Add Numbers)

To add scores in cells C2 to C4:

=SUM(C2:C4)

This calculates the total.

AVERAGE

To calculate the average score:

=AVERAGE(C2:C4)

COUNT

To count how many numbers exist:

=COUNT(C2:C4)

IF (Basic Condition)

To check if a student passed (score ≥ 80):

=IF(C2>=80, "Pass", "Fail")

This means:

If score in C2 is 80 or more → show "Pass"

Otherwise → show "Fail"

5️⃣ Data Types in Excel

Excel handles different types of data:

• Text (Names)
• Numbers (Scores)
• Dates (01/01/2026)
• Currency ($100)
• Percentage (50%)

6️⃣ Sorting and Filtering

Excel allows you to:

• Sort A to Z
• Sort smallest to largest
• Filter specific values

Example:

You can filter only students with Score ≥ 80.

7️⃣ Creating Charts in Excel

Excel can create:

• Bar charts
• Line charts
• Pie charts
• Column charts

Example:

If you select the score column and click Insert → Chart → Column Chart, Excel automatically creates a visual representation.

Charts help you:

• Identify trends
• Compare values
• Present data clearly

8️⃣ Real-World Example: Sales Data

Imagine you run a small shop.

Your Excel sheet might look like this:

| Product | Sales | Month |
|---------|-------|-------|
| A       | 200   | Jan   |
| B       | 150   | Jan   |
| A       | 300   | Feb   |

To calculate total sales for Product A:

=SUMIF(A2:A4, "A", B2:B4)

This means:

• Look in Product column (A2:A4)
• If product equals "A"
• Add corresponding sales from B2:B4

9️⃣ Why Excel Is Powerful

Excel is powerful because it combines:

• Storage
• Calculation
• Analysis
• Visualization

All in one place.

It is often the first step before moving to advanced tools like:

• Databases
• Business intelligence tools
• Programming languages
