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.
