Please do not check the “community wiki” box when posting a question. See Guidelines for asking - #4 by jimk.
According to Convert Pages documents to PDF, Microsoft Word, and more - Apple Support, Pages can read and write .docx files, as can LibreOffice.
Still, LibreOffice works best with .odt files. From
http://i-work-in-pages.blogspot.com/2012/10/open-openoffice-odt-files-in-textedit.html:
However, .odt or .fodt text documents
don’t open in iWork/Pages.If you encounter this problem, don’t
panic. TextEdit, the simple word
processor that comes pre-installed on
Macs, can open .odt documents. Click
on the file, drag it onto the TextEdit
icon in the Dock and it will open.You can then work on the document in
TextEdit or copy-paste it into Pages
if needed.
