✅ What is a Workbook in Excel?

An Excel Workbook is a complete Excel file. Just like a physical notebook contains multiple pages, a workbook contains multiple worksheets (also called sheets or tabs).
The file you save with a .xlsx extension is the workbook.

🗂️ Example:

When you open MyBudget.xlsx, you’re opening a workbook. It may have multiple sheets like:

• Jan Budget

• Feb Budget

• Summary

All of these sheets exist inside the workbook.

✅ What is a Worksheet in Excel?

A Worksheet is a single page within a workbook. It’s where you input your data in the form of rows and columns.

Each worksheet contains:

• 🟩 Cells (identified by column letter + row number like A1, B2)

• 🟦 Rows (horizontal – numbered: 1, 2, 3…)

• 🟨 Columns (vertical – lettered: A, B, C…)

👀 Real View:

When you open Excel, you typically see Sheet1 — this is your first worksheet.
