Pure Functional Programming in Excel • Felienne Hermans • GOTO 2016

This is the talk that I first saw that builds on that: [this video] I found it interesting, fun and great. Still, I would stick to using Excel for the personal analysis of data and not as the language/tool on which software is developed: data & programming logic intermixed, the default way to index cells, the difference between normal cells and array cells, and tables, etc., the fact that some things are just not possible to do fully programmatically without creating your own VB functions and therefore asking recipients of what looks like data to accept running arbitrary code in their machines, etc.
