Microsoft Excel Program
Microsoft Excel is a spreadsheet program used for storing, organizing and manipulating data. Spreadsheet software was originally based on paper charts used for accounting. Therefore, the basic layout of computerized spreadsheets is the same as paper ones. Related data is stored in small rectangular boxes or tables, which are collections of cells arranged in rows and columns. All versions of Excel can store multiple spreadsheets in one computer file. A saved computer file is often called a workbook, and each sheet in a workbook is a separate worksheet. When you look at an Excel screen or any other spreadsheet screen, you may see a rectangular table or grid of rows and columns.In newer versions of Excel, each worksheet has about one million rows and more than 16,000 columns. This requires an addressing scheme to keep track of where the data is located. Horizontal rows are identified by numbers (1, 2, 3) and vertical columns by letters of the alphabet (A, B, C). Columns after the last letter are AA, AB, AC or AAA, AAB, etc. can be. The intersection between a column and a row is a small rectangular box known as a cell. A cell is the basic unit for storing data in a worksheet. A cell reference is a combination of column letter and row number, such as A3, B6, and AA345. In these cell references, the column letter is always listed first. Creating a formula begins by entering the equal sign in the cell where you want the answer to be displayed. Formulas can also contain cell references to one or more table functions instead of data.
