Yes-ish. Work on at all, yes. Have full cross compatibility? Absolutely not. There are so many things that won’t retain formatting or features which plain don’t exist. For me, impress vs. powerpoint is a complete no go. I have to use office for work, so I just use powerpoint in a vm when I need it. And good luck ever working on anything with someone else. Office is an ever moving target. I sincerely, and unfortunately, doubt there will ever be a FOSS drop in replacement.
