A spreadsheet is a program that displays data in a table of rows and columns called a worksheet. It can be used to create budgets, financial statements, charts, and for inventory management. A worksheet contains cells at the intersection of rows and columns that can contain labels, values, or formulas. Formulas in cells perform calculations by combining numbers, cell references, and functions following the proper order of operations. Tools are available for adjusting cell size, copying data between cells, automatically summing ranges, and creating charts to visualize data. Data can also be sorted in ascending or descending order.
