What's weird about that? Excel is absolutely everywhere in finance, so if you have a special programming language that you consider to be part of your secret sauce it makes sense to integrate it into excel as well.

A friend who works as a at risk manager at a major bank sometimes shares horror stories about the giant spreadsheet they have for some part of their holdings. They have disabled the "automatic recalculation" feature because it takes over 48 hours to recalculate everything. This is after running it through a special excel compiler to speed it up.

Excel is everywhere used everywhere and for very important things.

I just never... thought about writing a Haskell plugin for it. It makes sense! Better than using some other language. Functional for Excel makes sense.

I love hearing horror stories about small (and large!) governments and companies abusing and misusing Excel. https://sheetcast.com/articles/ten-memorable-excel-disasters
