XLSThe content of a document typically includes statistical and numeric data tagged with text. Graphics or images can also be embedded into the rows and columns of a spreadsheet in .xls. Mathematical equations and other functions for calculating numerical data or statistics are also available as integrated features of Microsoft Excel. VB scripting via macros can also be done using XLS spreadsheets. Formatting properties and other layout elements can be implemented into new XLS spreadsheets by using XLT files (often called Excel templates). Microsoft Excel also has a version for the Mac platform. You can also use Microsoft Notepad or WordPad to open XLS files.

Microsoft Excel files use a proprietary format to store Microsoft Excel documents. This file format is called Binary Interchange File Format (BIFF). The data in all Office document files is stored in a series of fixed-size streams. The location of each fixed-size stream is described by several sector allocation tables. These streams contain metadata information about the document, such as author name, subject, and individual sheet names. XLS files can also be opened through Microsoft Excel Viewer and OpenOffice.
