Your developers build enterprise solutions  around Microsoft Office and its file formats.

They do this because Office is available on your desktops, and its file formats (Word docx, Powerpoint pptx and Excel xlsx) are an open (ISO) standard. 

Our mission is to provide libraries and associated support to maximise your developer productivity when manipulating Office files in Java or .NET.

Our approach is based on openness and ease of integration.  docx4j is open source (ASLv2), and it integrates readily with app servers and document management systems.  

With docx4j, you can unlock your data, and present it in documents, slides, and spreadsheets.
