In fact, the only spreadsheets that I've found so far that give 512 are Google Sheets and Gnumeric on Linux. Gnumeric is even kind enough to automatically insert parentheses to explicitly show 2^(3^2) as well as (-2)^2.

So, a few spreadsheets do -2^2 correctly and a few do 2^3^2 correctly, but I'm not aware of any spreadsheets that do both of these operations correctly.
