Welcome to the Grid
A spreadsheet is just a big grid of little boxes called cells. Each one can hold a number, text, a date, or a formula. Think of graph paper that does math for you.
Columns Run Up and Down
Columns are the up-and-down strips, labeled with letters across the top: A, B, C, and so on. After Z, they double up as AA, AB, AC.
Rows Run Side to Side
Rows run side to side, labeled with numbers down the left: 1, 2, 3. Row 1 sits at the very top, and a sheet can hold over a million rows.
Where Columns and Rows Meet
A cell is the box where a column and a row cross. Where column B meets row 3 is one exact spot that no other cell shares.
Every Cell Has an Address
Every cell has its own address, just like a house: the column letter, then the row number. So column A, row 1 is A1.
Reading a Few Addresses
To read an address, find the letter first, then the number. So B2 is column B, row 2. A cell's address never changes, no matter what you type in it.
The Name Box
The Name Box in the top-left corner always shows the address of the cell you've selected. Click any cell and watch it update.
The Active Cell
The cell you click on is the active cell, marked with a bold outline. Whatever you type lands there, so always check which cell is active first.
A Worked Example: Building a List
Here's a tiny product list: names go down column A, prices down column B. Each column holds one kind of data, and each row is one product.
Why the Grid Layout Matters
Letters and numbers let formulas point at exact cells. A clean grid, one data type per column, makes =B1+B2+B3 easy to write and read.
=B1+B2+B3Headers Keep You Organized
The top row usually holds headers that label each column, like "Product" and "Price." They keep your sheet readable for humans.
Quick Check
Test your understanding of how the grid is labeled.
Recap: The Spreadsheet Grid
Quick recap: columns use letters, rows use numbers, and a cell is where they meet. Every cell has an address like A1, shown in the Name Box.
