There are replacements that can do the same tasks and offer advantages over Microsoft Office (LibreOffice, Nextcloud Office, Collabora Office, Softmaker Office). Their main issue is that they aren't what everyone uses.
The other issue is that Microsoft Office itself respects neither the open document standard, nor their own published standard for the .docx format, so it's literally impossible for anyone outside Microsoft to make a 100% compatible program.

Nothing in EndeavourOS really "just works". You have to install and configure the stuff you need.
