Question about testing changes made to MS Word documents

How-dee!   I have a question about testing changes made to MS Word
documents.   Someone sent me a Word DOCX file that needed to be updated
and I managed to update it in LibreOffice Writer 7.1.5.2 on Ubuntu 21.04
Linux.  I wanted to test the saved file by loading it in MS Word.  Since
I don't have access to MS Office, I uploaded it to Word online using my
Hotmail account.  The document loaded but when I went to print it, the
generated PDF was pretty much trashed.

So, what's a good/reliable way to test changes saved in DOCX format in
Writer?   Is using Word online, as I did, akin to loading it in MS Word
2016?  I believe the document was last edited in MS Word 2016 before it
was sent to me.

Thanks in advance!

Peace...

What I did was install the free Word viewer.

Apparently, it's now called Doc Viewer.  I'm not sure how it compares with the Word viewer.

Thanks for the reply and for the link!  I'll try it out!
