Do you have support for creating and reading Excel 2016 files?
Thanks for your query.
Yes, it is supported. Aspose.Cells supports to read the Excel files which are created in MS Excel 2016. Similarly the files created by Aspose.Cells APIs would be opened fine into MS Excel 2016.
If you find any issue while reading/writing newer Excel files, let us know with sample code and template files, we will check it soon.
