What does the worksheet-function tag mean?
This tag is for spreadsheet questions where the question or answers involve an in-the-cell worksheet function, as opposed to some form of code.
Worksheet functions are usually like the following that you can type directly into the cell:
=YEARFRAC(DateOne, DateThree, Basis)
These are built-in to the cell functionality. This is opposed to if you have to write a script or macro to do some other calculation or such like.
The tag description is henceforth and shall be asking for answers where you do not have to write a macro, but instead are looking to use an in-built cell formula for the results.
