About formats

XLS is the binary spreadsheet format of Microsoft Excel, first introduced with Excel 1.0 for Macintosh in September 1985 and becoming the dominant spreadsheet format worldwide. The format stores workbooks as OLE2 compound document files using the Binary Interchange File Format (BIFF), organizing sheets, cells, formulas, formatting, charts, pivot tables, macros, and metadata across multiple internal streams. Each cell record encodes the cell's value (number, string, boolean, error, or formula), position, and formatting index, while shared string tables and style records reduce redundancy. The format evolved through BIFF versions (BIFF2 through BIFF8), with BIFF8 (Excel 97) establishing the structure used through Excel 2003. XLS supports up to 65,536 rows and 256 columns per sheet, a limit that drove the creation of XLSX. One advantage is universal spreadsheet compatibility — XLS files are recognized by every major spreadsheet application including LibreOffice Calc, Google Sheets, Apple Numbers, and dozens of programming libraries across all platforms. The format's mature feature set is another strength: XLS handles complex formulas, conditional formatting, data validation, named ranges, array formulas, external references, and VBA macros. Although XLSX replaced XLS as the default in Office 2007, the binary format persists in financial institutions, legacy reporting systems, and any environment where Excel 97-2003 compatibility is required.

OXPS (Open XPS) is a fixed-layout document format standardized as ECMA-388 in June 2009, representing an evolution of Microsoft's original XPS specification. The format packages fixed-layout pages, fonts, images, and metadata in a ZIP-based Open Packaging Conventions container — the same packaging framework used by DOCX, XLSX, and other Office Open XML formats. Each page is described using an XML markup language that specifies paths, glyphs, images, and canvas elements with precise coordinates, producing documents that render identically regardless of the viewing device or printer. OXPS incorporated several changes from the original XPS: the use of JPEG XR for high dynamic range images, support for the Open Packaging Conventions 2nd edition, and alignment with the Ecma standardization process. Windows 8 and later generate OXPS (rather than XPS) when printing to the Microsoft XPS Document Writer. One advantage is standards-based document fidelity — as an Ecma standard, OXPS provides a vendor-neutral, fully specified format for documents that must look identical everywhere they are rendered, essential for legal filings, regulatory submissions, and archival records. The fixed-layout model is another strength: unlike reflowable formats, OXPS documents preserve exact page composition including precise glyph positioning and vector graphics. Built-in support in Windows and the .NET framework provides native viewing and creation capabilities without third-party software.
