    Thank you Anton for this. I now have a tool I can use to convert Excel to PDF that works as I had described. With constant communication we have looked over well to ensure the app works as expected given I wanted it to support multilingual text. After installing I tried out a previous file and it gave a me a good result. Thank you again.
