seo - Sort keyword data to show highest searches with lowest competition -

i've used google adwords tool find suggested keywords. want take data step further:

is there formula or way sort data show highest searches lowest competition?

i'm looking create additional column output kind of rating, should show me best keywords target.

just note - i'm not going using adwords, me write targeted content.

update: i've created column , done searches/competition , sorted that... on surface seems give pretty results.

is there formula or way sort data show highest searches lowest competition?

warning: competition figure returned adwords competition between advertisers, not competition between content providers (which not available).

if want make money, should multiply search competition, because want people fight put ads on page.

if not going use adwords, formula makes sense (assuming competition figure between content providers).
