    A spreadsheet created with Microsoft Excel, an XLS Document File is used to store and display data in tabular form that can include text, numeric values, formulas, external data connections, images and charts. Although typically employed within business contexts to organize and analyze information more efficiently; they are equally suitable for personal use. There are two varieties of XLS files - XLS and XLSX - each using its own proprietary binary file format; while XLSX files use Office Open XML. While XLS files may be more compatible with older versions of Excel and can contain Macros, the latter provide better security, faster performance, smaller file sizes and quicker file access times. The Library of Congress houses over 389,000 XLS files in its digital collections, amounting to 226 gigabytes of data. Most of these XLS files were acquired as part of donated papers from individuals or organizations; these may contain datasets or supplementary materials related to published articles. Additionally, staff at the Library often create spreadsheets as aids for performing their duties more efficiently. Although XLS document formats can be read by several applications, Microsoft Excel remains the go-to application for opening these files. While Excel can be purchased across many operating systems, free and open-source alternatives that also open XLS files exist - Google Sheets works online across most OS platforms while WPS Office and OpenOffice Calc for Linux; Gnumeric for macOS; and Apple Numbers offer viable alternatives that support this format.
