DOCXOOXMLdokumenter

DOCXOOXMLdokumenter is a common name used in Scandinavia to refer to documents created with Microsoft Word using the Office Open XML (OOXML) format, also known as WordprocessingML. Introduced with Microsoft Office 2007, the DOCX format replaces the older binary DOC format and is part of the OOXML family that also includes XLSX and PPTX. The format was standardized by ISO/IEC as 29500, after ECMA-376 and subsequent revisions.

An OOXML document is a ZIP container that holds multiple XML parts describing content, styles, numbering, settings, and relationships. The main document content resides in word/document.xml encoded in WordprocessingML. Other parts cover metadata, images, fonts, themes, and header/footer. The packaging follows the Open Packaging Conventions, with .rels files describing relationships between parts.

Because it is a standardized, XML-based and zipped format, DOCX files are relatively compact, easy to parse, and support accessibility features and metadata. They support rich formatting, images, tables, charts, equations, comments, tracked changes, and content controls. Macro-enabled variants exist as DOCM to include macros; templates use DOTX or DOTM, while older binary DOC or RTF still exist but not DOCX.

Interoperability is generally good, but exact rendering can vary between applications; complex features and custom namespaces may not be fully supported in all tools. The standard's openness enables third-party tools and libraries, such as the Open XML SDK for .NET or Apache POI, to read and manipulate DOCX files programmatically. Security considerations include macros and links from external content.

Usage: widely adopted in business and education for document creation and collaboration. After introduction, the format became dominant for Word documents, with continued updates alongside Office releases. The term DOCX OOXML documents emphasizes the format rather than a single version or vendor.
