Default file format for saving in MS Office 2016: OOXML Transitional or Strict?

    Question

  • What is the default file format for saving in MS Office 2016? Is it still OOXML Transitional or did it change to ISO/IEC 29500 Strict?

    As was pointed out to me in the Office Forums [1], it's maybe better to post this question here.

  • Hi Cedric,

    Thanks for the question. The referenced article has an updated version here:

    https://technet.microsoft.com/EN-US/library/dd797428(v=office.16).aspx

    As you can see from this set of charts, the default is still the transitional WordprocessingML, SpreadsheetML and PresentationML and Microsoft Office 2016 still supports read/write of the strict (ISO/IEC 29500-1) markup standard.

    Does this answer your question?

  • Hi Tom

    Thank you for the link and your clarification, that's exactly what I needed!

    Already being here, I have a follow-up question:

    Are you aware of a turning away from this practice, let's say in a hypothetic Microsoft Office 2019? The versions 2010, 2013 and now 2016 are all saving in the transitional WordprocessingML, SpreadsheetML and PresentationML by default. For the purpose of security of investment I wonder if future versions will operate in the same way. It may however be too early to know.

    Sincerely,

    Cédric

  • Hi Cedric,

    I don't have information on future changes in the default file format for Office products but will update this thread if there's anything I find that can be shared.

    Thanks,

    Tom
