is it possible to update the LEAD checkbox in the contact window from checked
to unchecked to 1000 accts at once?

is there a line of code or something that must be entered? I accidentely
imported a new list of contacts with the field LEAD in my xls marked as 1 so
the box is checked but i began working and i realized i didn't want it to be
checked on those leads.

please advise.
