We
 are already using Aspose.Total (.NET) and now planning to also purchase
 the Aspose.Total (Java). Our primary usage is to convert various 
document types to PDF format. Before we make a final decision and place 
an order, we are exploring the Java version and have come across some 
issues which we want to discuss. 
When converting 
.xls and .xlsx files to PDF, we observed some improper results from Java
 API as compared to the results we get from the .NET API. It could be 
due to usage of evaluation version but still want your feedback on the 
issues.  Please see the attachment with sample input documents and the 
output from Java (evaluation) API and the .NET (licensed) API. 
Hi,
Thanks for considering Aspose.
I have tested converting both your files xls and xlsx, it works fine and give similar results (approx.) to .NET results.
I have also attached the resultant PDF files here for your reference.
Thank you.
