HI,
I was looking for exporting the Excel file to the PDF using the Docx4j but i found there is no XSLT Template created for the Excel xml to the FOP XML for PDF Creationg ,if anybody attempted in doing so please let us know share with us.We are in process of making excel to pdf conversion using the open source solutions like FOP|POI| or and DOCx4j.
I See this Functionality is not supported via docx4j yet, If Some one writes the XSLT Template for this than it will be a starter for exporting the excel to pdf.
Currently there is no good opensource solution which does this. there are few paid version solutions which will do this
