That's what excel is; code for people who don't know they're writing code - and its clearly a bad way of doing most of the things people do with it.
But on the flipside you have to give it props for getting people a foot into programming, even if they don't realise that's what they're doing (and folks who use actual languages and lines of text to achieve the same thing don't accept it for what it kinda is).
I think you could make an argument that Excel is the world's most used/successful IDE ;)
