Microsoft Excel is an electronic spreadsheet program. You might of heard the terms "spreadsheet" and "worksheet". People generally use them interchangebly. To remain consistent with Microsoft and other publishers the term worksheet refers to the row-and-column matrix sheet on which you work upon and the term spreadsheet refers to this type of computer application. In addition, the term workbook will refer to the book of pages that is the standard Excel document.The workbook can contain worksheets,chart sheets, or macro modules.

An Excel list provides features designed to make it easier to manage and analyze groups of related data in a worksheet. When you designate a range as a list, you can manage and analyze the data in the list independently of data outside the list. For example, using only the data contained within the list, you can filter columns, add a row for totals, and even create a PivotTable report, using only the data contained within the list.
