As a (temporary?) alternative for 32-bit TCL users, consider gnumeric (for spreadsheets) and abiword (for word processing).
Even though I run Pure64 on my personal machine, I've been using gnumeric for a while (to avoid all the dependencies of libreoffice) and have found it to be a drop-in replacement for libreoffice-calc. My wife and I share some spreadsheets (.ods files) and we have no problem with the same file going back and forth between her libreoffice-calc and my gnumeric.
