Make node/field text input format available to Views
It is possible to do this with Views 3 in Drupal 7:


Add the field you need the format of to the view (E.g. field_body)
In the configuration form for that field tick the 'Rewrite the output of this field' box
Put the '[field_name-format]' token into the box


It will render the raw name of the input format, instead of the value.
