It's quite easy to use Mathematica directly to format the information
the way you request.  For example:

data = {CountryData["Countries", "Name"],
   CountryData["Countries", "GDPPerCapita"],
   CountryData["Countries", "LifeExpectancy"]};
data = Transpose[data];
Grid[data]

Note that the page you link to contains a "Mathematica form" button,
that indicates how to get some of this information.  The graph on that
page, with tooltips indicating country name, can be generated as
follows:

toLabeledPoint[{name_, gdp_, le_}] := Tooltip[
  Point[{gdp, le}], name];
Graphics[toLabeledPoint /@
  Select[data, NumericQ[#[[2]]] && NumericQ[#[[3]]] &],
 AspectRatio -> 1, Axes -> True]
