It has nothing to do with your particular situation. This is a reasonable assumption to make if somebody comes and wants a solution in Excel.

But ok. So what you are saying your Excel was reviewed by somebody else. How is this any different from reviewing somebody else’s code?

I work in a company where even the least technical analysts are capable of using numpy. We have libraries to use Google Sheets as input-output data. So you get the best of the two worlds.

What does Excel resolve here?
