Excel is a powerful tool for getting meaning out of vast amounts of data. The key for unlocking all that potential is the grid of cells. Cells can contain numbers, text or formulas. You put data in your cells and group them in rows and columns. That allows you to add up your data, sort and filter it, put it in tables, and build charts. In addition, it can display data as line graphs, histograms and charts, and with a very limited three-dimensional graphical display.
