I wonder whether there exist a way to know with which Microsoft word version a .docx file was saved.

Reason: Microsoft Word tend to add new features, so I prefer to open a Microsoft Word document using Microsoft Word version at least equal to the one that was used to create/save the document:

    Why would you want to know? The format is backards compatible and it should load in any version from Office 2010 and up regardless.

  • @LPChip how about Microsoft Office 2007? Nov 10 '16 at 15:58

    I believe office 2007 is included. Microsoft made the format standard so it can be loaded by other programs too. Basically, any program that can load a .docx can undesrtand it fully.

  • @LPChip Thanks, how can Microsoft add features to Word, if docx can be loaded without any loss in Microsoft Word 2007 or 2010? Nov 10 '16 at 16:21
  1. Make a copy of the *.docx file and change the extension to *.zip.

  2. Open the zip file.

  3. Open the docProps\app.xml file.

  4. Look at the end for the AppVersion tag value:

    • 12.0000 = Word 2007
    • 14.0000 = Word 2010
    • 15.0000 = Word 2013
    • 16.0000 = Word 2016

    A .docx file created by MS Word 2003 also shows <AppVersion>12.0000</AppVersion> but <Application>Microsoft Office Outlook</Application> instead of "Microsoft Office Word". A .docx file created by LibreOffice has no AppVersion field; instead, the version is part of the Application field, e.g., <Application>LibreOffice/$Windows_X86_64 LibreOffice...</Application>. A .docx file created by Win10 Wordpad contains no docProps\app.xml file at all. I've seen a .docx file created by Word for Mac with <AppVersion>15.0000</AppVersion> and <Application>Microsoft Macintosh Word</Application>. Apr 9 '20 at 20:26

I just want to mention that LPChip is 100% wrong. If e.g. you open 2010 created document with 2007 Word, then you will not see any elements/effects because they are not supported. See this list for reference: https://support.office.com/en-us/article/Open-a-Word-2010-document-in-an-earlier-version-of-Word-adfe6ca1-7b18-45a2-ba05-cb1b00ad9935

    The list isn't that long. You could easily cite and quote it. "I just want to mention that LPChip is 100% wrong. " - is a comment and should be removed from your answer. An answer should, just answer the question, the fact LFChip is wrong is evident by the fact your saying something that doesn't agree with him. You should not call out other users, in an answer, and say they are wrong (even if they are wrong). Hint: The majority of the table is no change, so you can simply list what changed, and another list of what didn't change.
