Spreadsheet
Alternatively referred to as a worksheet, a spreadsheet is a data file made up of rows and columns that are used to sort data and allow a user to manipulate and arrange data easily, commonly numerical data. What makes a spreadsheet software program most unique is its ability to calculate values using mathematical formulas and the data in the cells. A good example of how a spreadsheet may be used is creating an overview of your bank's balance. Below is a basic example of what a Microsoft Excel spreadsheet looks like.
