question about Word document sending/saving

[Myword]

Those of you who use Word 2019 and newer, which document file do you use for your
papers? A list is offered, including Worddocument, Open XL and many others. What's the difference?
 I ask because
 I sent a paper to a editor and she said it cpntained garbage encoded nonsense,
using XL. So I had to paste the whole text and send it. Okay for now, she said.
   I never saw coded nonsense in my work.   I use Word365 new. PC.

Was the DOS extension of your submitted MS Word file .docx  ?

Always use .docx

Yes, I always use .docx. Earlier versions of Word are compatible with later ones, but not necessarily vice versa (some fonts, in particular, may not exist in previous versions, and when the document converts to the earlier version you can get weird stuff. Especially if you use non-Latin characters or mathematical symbols.

Or you can send a pdf, which will always display correctly.

.docx or a pdf file, the latter if you want formatting and tables to display accurately.

Most journals I Have been submitting to recently ask for both a .docx AND a PDF version of the main manuscript...
