Each individual box on a spreadsheet is known as a cell. Each cell is identified by a letter and a number. For instance, the first cell is A1, which is column A and row 1. Columns are along the top, and rows are down the side. If I wanted G3, I would go along to the column marked G and then down the G column to row 3. If I then click on G3, that cell becomes active.
