About formats

DOT is the binary template format for Microsoft Word, using the same OLE2 compound document structure as DOC files. A DOT file contains a complete document framework — styles, page layout, margins, headers and footers, boilerplate text, macros, AutoText entries, toolbar customizations, and keyboard shortcuts — that serves as a reusable foundation for creating new documents with consistent formatting. When a user creates a new document based on a DOT template, Word generates a fresh untitled DOC pre-populated with the template's content and styling while leaving the original template file unmodified. The format supports every feature available in DOC, including complex formatting, embedded objects, form fields, and VBA macro code. The Normal.dot file holds particular significance as Word's global template, storing default styles, macros, and customizations that apply to all new blank documents. DOT templates became essential to enterprise document management, ensuring that legal contracts, business letters, technical reports, and corporate communications consistently adhered to organizational formatting standards. One advantage is brand and compliance consistency — distributing DOT files across an organization guarantees uniform document appearance without relying on individual users to manually configure styles and layouts. While the XML-based DOTX format has replaced DOT for modern workflows, the binary template format remains in use in environments requiring Word 97-2003 compatibility and in legacy template libraries.

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.
