Unreadable docx file

I try to convert a pdf file using Aspose pdf java version.
The file is created but when I try to open it using word 2016 I get an error : the file is corrupted and cannot be opened.
Trying to open the same file with LibreOffice the file is opened but the layout is not correct.
Please help
Tks
