Felienne Hermans actually implemented a Turing machine in Excel, without using scripting: http://www.felienne.com/archives/2974 http://www.felienne.com/archives/2974 There was an HN post about this in September 2013: https://news.ycombinator.com/item?id=6416631 https://news.ycombinator.com/item?id=6416631

It looks like it uses one row per step. Excel supports finite rows, and hence this does not prove that Excel is Turing complete. A program like while(true); will eventually run out of rows and terminate.
