Microsoft Excel is featured under the Microsoft Office Suite programs that include Microsoft Word, Microsoft PowerPoint and Microsoft Outlook. The Microsoft Excel software was launched in the 1980s and is now one of the most popular spreadsheet programs to date. It has been designed to allow users to develop formulas, create graphs and tables from data entered and calculate figures. It has been updated since its previous version was released to include a new OLED connector, Lasso Select, support of percentage data entry as well as the option of working with a Surface pen on a touch-enabled device. Features such as Function Authoring and OData connector as well as others have been greatly improved in the Microsoft Excel 2018 version.
