About formats

DOC is the binary document format of Microsoft Word), the word processor first released in October 1983 for MS-DOS and later becoming the dominant document creation tool worldwide. The format stores documents as OLE2 compound document files — a binary container with multiple internal streams holding text content, formatting information, embedded objects, macros, and metadata. The text stream uses a complex system of formatting runs, section descriptors, paragraph and character property tables, and style definitions to represent arbitrarily complex document layouts including columns, headers, footnotes, tables, floating images, tracked changes, and mail merge fields. The format evolved substantially through Word versions, with Word 97 establishing the binary structure that remained standard through Word 2003 and created the .doc files most commonly encountered today. One advantage is near-universal compatibility — DOC files can be opened by virtually every word processor and document viewer across all platforms, from Microsoft Office to LibreOffice, Google Docs, and Apple Pages. The format's rich feature support is another strength: DOC handles complex layouts, embedded OLE objects, VBA macros, and revision tracking that power enterprise document workflows. Although Microsoft introduced the XML-based DOCX format with Office 2007, DOC remains heavily present in existing document archives and continues to be produced by organizations maintaining compatibility with older Word installations.

XLSX is the default spreadsheet format for Microsoft Excel since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and adopted as ISO/IEC 29500. An XLSX file is a ZIP archive containing XML documents that describe workbook structure, sheet data, styles, shared strings, formulas, charts, pivot tables, and relationships between components. Each worksheet is stored as a separate XML part where cells are organized by row and column references with typed values and style indices. The XML foundation enables programmatic spreadsheet creation and manipulation using libraries like openpyxl (Python), Apache POI (Java), and ClosedXML (.NET) without requiring Excel. XLSX dramatically expanded capacity compared to XLS: over 1 million rows and 16,384 columns per sheet, enabling use cases previously impossible in the binary format. One advantage is openness and cross-platform support — the documented OOXML specification enables implementation by LibreOffice Calc, Google Sheets, Apple Numbers, and numerous specialized tools. Built-in ZIP compression is another practical strength: XLSX files are typically 50-75% smaller than equivalent XLS files, and the modular XML structure improves data recovery when files are partially corrupted. The format supports modern Excel features including structured tables, slicers, sparklines, Power Query connections, and real-time co-authoring. XLSX has become the standard format for spreadsheet data interchange across business, scientific, and government domains.
