Thanks for your inquiry. Aspose.Words does support MS Word 2013 documents. Aspose.Words
supports all major OOXML versions for example OOXML ECMA-376 and OOXML
ISO/IEC DIS 29500. OOXML WordprocessingML documents most often come as
DOCX files, which are ZIP packages and Aspose.Words does support DOCX
However, we have not officially announced the support of Word 2013 documents. We will inform you via this forum thread when we announce the support of Word 2013 document. Regarding MS Word 2016 document, I am afraid we cannot share any timeline without knowing the features and enhancement in MS Word 2016.
We apologize for your inconvenience.
