How to Use Excel Functions in Access:
It would be very nice if I could call an excel function like yield directly
from a query.
Can this be done? If so, how?
Well, there are Excel functions and then there are Excel Add-ins (which
unfortunately includes Yield). The core worksheet functions can be included
as follows:
1. Open your database, type Ctrl+G to make sure you're in the VBA editor.
2. Choose Tools\References, and scroll down and check Microsoft Excel 10.0
Object Library (or whatever version of the Excel Object Library you have)
3. Use the functions as Excel.WorkSheetFunction.FunctionName, for example if
you type:
?Excel.WorksheetFunction.Ceiling(5,3)
in the immediate pane and hit enter, it should return 6.
4. To use such functions in queries, make a wrapper function by passing
appropriate data to the Excel function and returning the results, for
example:
Function MyCeiling(ByVal iOne As Double, ByVal iTwo As Double)
MyCeiling = Excel.WorksheetFunction.Ceiling(iOne, iTwo)
End Function
5. Call that wrapper function from queries, as in:
Result: MyCeiling([field1],[field2])
The Yield function, however, is a special case, as it's an Excel Add-in. If
you're *really* intent on using it, you can access it from automation, see:

Probably best to develop your own library of functions: there are VB/VBA
versions out there for almost anything that you might need.

I would like the data to simply be placed on a worksheet
that I've already spent time formatting (i.e. column widths, bolded column
headings...etc.)
Is there a way to do this?
You can't do this with TransferSpreadsheet.
You'll need to write VBA code that uses Automation to control Excel and
ensure
that the data ends up where you want it.
If you're new to Automation, here's a useful article giving the
basics of controlling Excel from Access:

Recent versions of Excel have a Range.CopyFromRecordSet method
that can be very handy for importing data from Access.
