A Spreadsheet is a computer program that imitates a paper worksheet. It shows a large sheet (like a sheet of paper) that has many cells in a grid of rows and columns. Users can put words or numbers into the cells, to make headings and store information (usually numbers). You can also move the grid lines around so that some cells are bigger than others, and change the color or size of text/font, the same way font/text is changed in a word processor. You can even put pictures in the worksheets, make multiple pages, and print out their results on real paper.
