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.

POTX (PowerPoint Template XML) is the Open XML template format for Microsoft PowerPoint, introduced with Office 2007. A POTX file is a ZIP archive containing XML parts that define slide masters, slide layouts, theme colors, theme fonts, theme effects, placeholder configurations, and default content — everything needed to establish a consistent visual foundation for new presentations. When applied, a POTX template creates a new PPTX document inheriting the template's complete design system, including multiple slide layout variants (title, content, two-column, comparison, blank, and custom layouts) each with precisely positioned placeholders. The XML-based structure brings advantages over the legacy POT format: templates can be inspected and modified using standard XML tools, design elements are cleanly separated into dedicated files (theme.xml, slideMaster.xml, slideLayout.xml), and built-in ZIP compression yields smaller file sizes. One advantage is design system management — POTX files encapsulate an entire visual identity as a distributable package, and the modular XML structure makes it straightforward to update individual elements like color schemes or font stacks without rebuilding the entire template. Broad compatibility is another strength: POTX templates work in PowerPoint on Windows and macOS, LibreOffice Impress, and online platforms. The format integrates with PowerPoint's template gallery and organizational template libraries, enabling centralized design governance across large teams.
