About formats

DOTM is a macro-enabled template format for Microsoft Word, introduced with Office 2007 as part of the Office Open XML family. DOTM combines the template functionality of DOTX — providing reusable styles, page layouts, boilerplate content, and formatting definitions — with the ability to embed VBA macro code that executes in documents created from the template. The format is a ZIP archive containing XML parts for styles, document defaults, and theme definitions, plus a vbaProject.bin stream for the VBA project. This combination enables organizations to distribute not just visual consistency but also functional automation: every document created from a DOTM template inherits both the formatting framework and programmatic capabilities. Common use cases include templates that auto-populate document fields from corporate directories, enforce naming conventions, generate tables of contents, insert dynamic headers with project metadata, or validate document structure before submission. One advantage is embedded workflow automation — a DOTM template can include initialization macros that configure the document environment, register custom ribbon commands, and connect to data sources the moment a new document is created from it. The distinct .dotm extension allows administrators to apply differentiated trust policies for macro-containing templates versus standard DOTX files. DOTM is supported exclusively in Microsoft Word desktop editions where VBA execution is available.

PPTX is the default file format for Microsoft PowerPoint presentations since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and later adopted as ISO/IEC 29500. A PPTX file is a ZIP archive containing XML documents that describe slide content, layouts, themes, relationships, and metadata in a structured, human-inspectable hierarchy. Each slide, slide layout, and slide master is stored as a separate XML part, with media assets (images, audio, video) and embedded objects kept in dedicated directories within the package. The XML foundation enables programmatic creation and manipulation of presentations using standard XML tools and libraries — developers can generate, modify, or extract content from PPTX files without requiring PowerPoint itself. One significant advantage is openness and interoperability: the fully documented OOXML specification allows any software to read and write PPTX files, and the format is supported by LibreOffice Impress, Google Slides, Apple Keynote, and numerous other tools. Built-in ZIP compression is another practical strength — PPTX files are typically 50-75% smaller than equivalent PPT files, reducing storage and transfer costs. The format supports all modern PowerPoint features including SmartArt, 3D models, morph transitions, embedded fonts, accessibility metadata, and co-authoring capabilities. PPTX has become the standard interchange format for presentation content worldwide.
