<h3>What is spreadsheet?</h3>
A spreadsheet is a computer program that allows you to compute, organize, analyze, and store data in tabular form. Spreadsheets were created as electronic counterparts to paper accounting spreadsheets. The software runs on data entered into table cells. Each cell can include numeric or text data, as well as the results of formulas that calculate and display a value dependent on the contents of other cells. One such electronic document may also be referred to as a spreadsheet.
Spreadsheet users can change any recorded value and see how it affects calculated numbers. Because of this, the spreadsheet is ideal for "what-if" analysis because many situations may be studied quickly without human recalculation. Modern spreadsheet software can include numerous interacting sheets and display data as text and numbers or as graphics.
