Spreadsheets are used to process and perform calculations of raw data. They are used frequently in the fields of business and accounting.
A spreadsheet appears as a grid where the rows are numbered and the columns are marked with letters from A to Z, then AA to ZZ and so on.
Since a spreadsheet allows for calculations on data, the parameters can be changed and manipulated in order to produce forecasting and modeling, often used in areas such as budgeting and sales. Graphs and charts can be produced from the results. The data can be merged with email functions to produce mailing lists.
