A computer application that replaced paper worksheets is called a spreadsheet. It shows multiple cells that together make up a grid consisting of rows and columns, each cell containing either alphanumeric text or numeric values. A spreadsheet cell may otherwise hold a formula that classifies how the contents of that cell is to be calculated from the contents of any other cell (or combination of cells) each time any cell is updated. Spreadsheets are often used for financial information because of their capacity to re-calculate the entire sheet automatically after an alteration to a single cell.
