Excel is either brilliant or horrible (depending on your role in dealing with the output) at being re-purposed to do "the wrong thing".

I've had form templates sent to me in Excel because of the easy-to-use table layout controls. I've had games sent to me in Excel because VBA was so damn easy to program simple ideas in. I've had PoCs of algorithms sent to me in Excel because the graphical chaining of each step is so illustrative.

I've also seen the nightmare that haunts businesses who define their business logic through a bunch of interconnected Excel files. As an aside, this seems like an area ripe for "disruption" (remember when "disruption" was a bad word?), which is where tools like excel_to_code could probably make a large impact. If you could validate and test the entire business logic, as expressed in Excel files, you could reduce or eliminate the "Excel defined business rules" nightmare. If you can do this, there are thousands of SMEs that will be knocking at your door.

I personally don't use Excel for much, and I used to deride people who used it for "the wrong task", but I've recently had to swallow my pride, and accept that it's a serious power tool for most non-programmer people. I'd even go so far to say that it's the most successful "visual programming" tool out there. And by a long way.
