📚 Excel Workbook Operations: Your Digital Filing Cabinet

🏠 The Big Picture: A Home for Your Data

Imagine you have a magic filing cabinet that can hold thousands of folders, and each folder can have many sheets of paper inside. That’s exactly what Excel is!

• Workbook = The entire filing cabinet (your .xlsx file)
• Worksheet = Each folder/tab inside that cabinet

When you open Excel, you’re opening a brand new filing cabinet ready to organize your world!

📖 Chapter 1: Workbook vs Worksheet — What’s the Difference?

🗄️ Think of it Like a Notebook

🎯 Simple Example

📁 My_Budget.xlsx (This is the WORKBOOK)
├── 📄 Sheet1: January Expenses
├── 📄 Sheet2: February Expenses
└── 📄 Sheet3: Summary

Key insight: One workbook can have MANY worksheets. Just like one notebook can have many pages!
