A spreadsheet is an interactive computer application program for organization and analysis of data in tabular form.
Spreadsheets developed as computerized simulations of paper accounting worksheets.The user of the spreadsheet can make changes in any stored value
and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated
without tedious manual recalculation. Modern spreadsheet software can have multiple interacting sheets,
and can display data either as text and numerals, or in graphical form.
The program operates on data represented as cells of an array, organized in rows and columns.
