OptionalhideSuppresses the single quote prefix on string values, returning bare display values instead.
OptionalshowReturns what formula view displays rather than the formatted value.
A formula cell returns = + its formula text, a cell spilled INTO returns '' (only the
anchor shows the formula), and every other cell returns its raw value with no number format
— a m/d/yyyy cell returns 45292, a 0.00% cell 0.125. That last rule is stricter than
useFormattingCategory, which is the formula BAR's text and keeps dates and percents.
Takes precedence over useFormattingCategory and hideStringPrefix: formula view applies neither a number format nor a string prefix.
OptionaluseOnly uses the minimum formatting, ignoring number formatting, returning the underlying value with minimal decoration.
