After I click on File-New, Excel will begin with a default size empty
sheet. If I type a long, say 100+ character, string into cell A1 then
that text will visibly spill over in the adjacent cells.

Is there a way to tell Excel to resize or redimension cell A1 so that
my string completely fills the cell in a nice looking manner??? I
basically want any arbitrary string that I type to completely visible
and contained within cell A1 in a nice looking way.

thank you
