text: **Introduction to the Office (2024) Fixed-Format**
  **Export Feature**
  
  This article explains how third-party software developers can hook in to the fixed-format 
  
  export feature available in the Office 2024, Office LTSC 2024, Microsoft 365 Version 2408 
  
  and later applications so that they can add their own exporter. 
  
  The applications include built in exporters for Microsoft XML Paper Specification (XPS) 
  
  and Portable Document Format (PDF). Fixed-file formats expose the content of a 
  
  document in a paginated form that is both application-independent and platform- 
  
  independent. 
  
  Software developers can add their own exporter, by writing an Office add-in that 
  
  implements the**IMsoDocExporter**COM interface. This article describes 
  
  **IMsoDocExporter**and its interaction with a hosting Microsoft 365 application, such as 
  
  Word. 
  
  Fixed-format export has been available since the Office 2007 release, and this article 
  
  includes information on the features that are new in the Office 2024, Office LTSC 2024, 
  
  Microsoft 365 Version 2408 releases.
