"doc" and "docx" are the same file format. Did you try that smart service?

Stefan Helzle · Answer

If your Word documents are stored in the binary file format "Word 97-2003 Document", then that smart service will not work. It only works with the XML based document file formats. 
 I suggest to check the app market for plugins.

 Yikes, this isn't true, and it's not even close. 
 ".doc" is the (much) older, proprietary format; ".docx" is the open, XML / WordML based format (which is just a ZIP container containing plaintext human-readable XML files you can open and edit). A convertor that recognizes DOCX files wouldn't have the first clue how to deal with a .doc file. And if a document is actually docx but has been named with the .doc extension, that is a severe type mismatch.
