Update document and convert document controls for Office 365 version
These functions are available in 2013 version but not in O365 yet. Will they be available for Office 365 in the near future?
This capability has been released as the Document Generation actions. Document generation automates document generation from one or more templates with conditional inclusion. See Document generation help for more information.

Document Generation only supports Open XML file formats. Converting a .doc to a .docx is still unsupported and needed in some scenarios.
