How can I open LibreOffice .dat files?
For example, I have a ~/.config/libreoffice/4/user/autocorr/acor_en-US.dat file. It isn't plain text; opening it as text gives back gibberish.
How can I open it?
acor_en-US.dat is a ZIP file so any uncompression tool that supports zip; like gunzip.
One tool you can use is GNOME Archive Manager (file-roller) to either view the files from within the archive or extract the archive.
