There was a time when people would use a gigantic book to keep track of all kinds of important data.  This data whether financial or some other sort of data added up after a while and took forever to calculate with the more data that was added.  To store years of important data companies often found themselves stocking shelf after shelf with these ledgers.

Think of Microsoft Excel as an electronic desktop where users can open and close as many electronic ledgers as they want. In reality it is a spreadsheet application designed by the Microsoft Corporation to allow users the ability to easily create organized ways of tracking numbers and data in one central location.

Excel created workbooks to replace the ledgers once used by some of the most important businesses. These workbooks will allow users to store a collection of related worksheets into one central file to quickly be accessed at any time.  Within these workbooks are items such as worksheets, charts and graphs.

Excel Worksheets were created by Excel to teach excel users how to create custom and predefined formulas and calculations of commonly entered important data.  An Excel worksheet is just a table-like structure of rows and columns split into cells. 

These cells are what users within Excel can use to enter and store data such as business once entered into the ledger.  Cells can also be used to create and calculate formulas based off the need of the specific user. Cells can also be used to create tables, graphs and charts of related data to better represent the information provided within their workbook.

Tools such as print preview and other unique ways of viewing allow the users to preview different parts of their workbook before the print or export their workbook to various resources.

Tools such as sort and filter allow users to hide or show select item based on key criteria. The types of way users can sort or filter these items is practically endless.

Advanced users of Excel can learn how to use macros to create custom made commands to repeat commonly used actions or calculations.  Macros can even transfer from one workbook to another or can be edit and delete to adapt to any changes that should come up in the future.

Advance users of Excel can also use the programming language known as Visual Basic to manipulate the Workbook and other parts of their computer in practically an unlimited amount of ways.

New versions of Excel have begun to allow even more customization by adding features such as the Ribbon, Quick Access Toolbar and Backstage view to allow Excel users the ability to customize practically every aspect of Excel.
