📂 Workbook vs Worksheet

A Workbook is the entire Excel file that contains one or more Worksheets. Think of it like a book with multiple pages. Each worksheet is an individual tab within the workbook where you work with your data.

• Workbook: The .xlsx file that stores all sheets.
• Worksheet: Individual spreadsheets within a workbook (Sheet1, Sheet2, etc.).

🔢 Understanding Rows, Columns & Cells

Excel organizes data in a grid of rows and columns. The intersection of a row and column is called a cell.

• Columns: Labeled A, B, C… up to XFD (16,384 columns)
• Rows: Numbered 1, 2, 3… up to 1,048,576 rows
• Cells: Each cell has an address, e.g., A1, B2, etc.

📁 Saving and Opening Excel Files

• To Save: Use Ctrl + S or click File > Save As
• To Open: Use Ctrl + O or File > Open
• Excel files have the extension .xlsx (or .xls for older versions)
• You can also export to .csv or .pdf formats
