Yes, this is expected. By default, Aspose.Cells will work in evaluation mode. When you use Aspose.Cells for Java API without setting/using a valid license, the output files and rendered image would have evaluation watermark. You need to have a valid license and set it in code (first) then you can use the product without this and any other limitations.

Either you may purchase the product to get the license or you may apply a free 30-days temporary license for Aspose.Cells for Java API for the time being to evaluate the APIs with full capacity without any limitation.

Moreover, see the document on how to set the license for your reference.

Should you have any further queries, feel free to write us back.
