A VBA function called from a worksheet can only return a value, it
cannot modify the environment in any way. In particular, it cannot
change cell formats.

If i am using a user defined function (VBA code)

i.e.

Function TestFunc(Input Variables etc...) As Variant

'Code here

TestFunc = "Result of Code"

End Function

How is cell formatting applied similar to the way the
excel function PMT() changes format to red if output

value

is negative.
