XML file converter for Microsoft Word for Mac

Hmm, you're right. I just tried this with Word 2016 on my Mac and had the same issue as you. Obviously something has changed, but since I normally do not use Word for edit XML files, I wasn't keeping up so I apologize for providing you with an erroneous set of instructions.

As a work-around, I tested this procedure and it worked:

1. Open the XML file in the TextEdit app.
2. Use <command><A> to select everything in the file, and then, use <command><C> to copy it.
3. Open Microsoft Word and create a new blank document.
4. Click on Edit in the file menu, and then, click on Paste Special.
5. If available, choose the "HTML Format" option and click on it. This should paste the XML over to the blank document in its original form. Note: In my case, Paste Special only recognized the XML as "Unformatted Text."
6. Click on OK to paste the text to the Word document.
7. Save the document in whatever format you prefer.

Have you tried simply doing the following steps?

1. Open Microsoft Word.
2. Open the XML file you want to convert. To do this, click the on the File menu > Open, and then, double-click the XML file.
3. Click on the File menu.
4. Click Save As.
5. Click Browse.
6. Select Word Document from the "Save as type" drop-down menu.
7. Click Save.

Yes there are a number of XML "formats," even though XML files are nothing more than simple text files that should be "machine" readable with any text editor, you may have a version that cannot be.

Sorry, I couldn't help. I know that there are numerous articles on the Internet that offer solutions for XML to Word conversion so you may have better luck that way or, as you originally posted, someone here may have already tried some of these and can offer a recommendation.
