While Excel will shrink to fit, there's no corresponding 'expand to fit'.
However, you can achieve the same effect. Just make your source data large
(for example, by increasing the font size). In Page Setup, select Fit to one
page wide and one tall. Excel will then fill the page, no matter the
orientation.

I have data that comfortably fits in one page in Portrait orientation.
However, there's plenty of space on the sides that is available to expand
the
data into, thus making the data larger and more visible. The data has been
centered vertically and horizontally.

Is there a way aside from margins, to enlarge/expand the same centered
data
to fill the sides while maintaining it in one page?
