The Excel Interface: Ribbon, Cells & Sheets¶

When you open Excel you see a grid of cells and a toolbar at the top. Let's name the parts.

The Excel workspace: ribbon at the top, the cell grid below, and sheet tabs at the bottom

The Key Areas¶

Part	What it is
Ribbon	The tabbed toolbar (Home, Insert, Formulas…)
Name Box	Shows/jumps to the active cell address (e.g. `B2`)
Formula Bar	Shows and edits the active cell's contents
Cell grid	The worksheet of rows and columns
Sheet tabs	Switch between worksheets in the workbook
Status bar	Quick stats (Sum, Average, Count) at the bottom

Workbook → Worksheet → Cell¶

Workbook (the .xlsx file)
 └─ Worksheet (a tab/sheet)
     └─ Cell (one box, e.g. C5)

A workbook is the whole file.
A worksheet (or "sheet") is one tab inside it.
A cell is a single box, addressed by column letter + row number → C5 is column C, row 5.

Columns, Rows & the Active Cell¶

Columns run vertically and are labeled with letters: A, B, C … Z, AA, AB …
Rows run horizontally and are numbered: 1, 2, 3 …
The active cell has a green border; whatever you type lands there.

Tip

The Name Box (far left, above the grid) always shows the active cell's address. Type an address like Z100 into it and press [[Enter]] to jump straight there.
