The Office Open XML (OOXML) file format, standardized as ECMA-376 and ISO/IEC 29500, has become the default document standard for modern productivity suites, including Microsoft Office (2007 onwards), LibreOffice, and Google Workspace exports. This paper investigates the internal architecture of OOXML ( .docx , .xlsx , .pptx ) as a ZIP-compressed package of XML files. We focus specifically on the challenges and best practices for implementing server-side "download" functionalities that generate OOXML files dynamically. The paper analyzes performance bottlenecks, memory management, security vulnerabilities (including XML External Entity attacks and ZIP bombs), and compliance with strict transitional schema. Empirical results demonstrate that stream-based generation combined with deferred XML serialization reduces memory overhead by 74% compared to naive DOM-based approaches. Finally, we provide a reference implementation for a secure, scalable OOXML download endpoint in a RESTful architecture.

A malicious .docx upload (if your system re-uploads user files) may contain a document.xml compressed from 1 KB to 1 GB inflated. When your server processes it for download generation, memory is exhausted.
