Countif has 49 questions total. Of those, 47 also have an excel tag. One has a libre office tag. And one only has it (countif).

There's no description or summary of the tag and it's not very useful. I don't know if "countif" exists in other scenarios with other programs, but right now it's a useless tag.

My Suggestion-

All countif tags should be replaced with worksheet-function if not already tagged with that. And then burninate Countif

Also, I couldn't think of a more clever title - I welcome an improvement.
