Detailed explanation-1: -Every worksheet is made up of thousands of rectangles, which are called cells. A cell is the intersection of a row and a column-in other words, where a row and column meet. Columns are identified by letters (A, B, C), while rows are identified by numbers (1, 2, 3).

Detailed explanation-2: -These letters and numbers are called row and column headings.

Only one cell is active at a time. The active cell is the cell surrounded by a black border. Data can only be entered into the active cell.

Column headers range from A-XFD, as Excel spreadsheets can have 16, 384 columns in total. Columns run vertically in the worksheet, and the data goes from up to down.
