The purpose of this module is to give site administrators the ability to change the input format of nodes en-masse. In particular it helps to solve the issue of users not being able to edit content they have created because the administrator has inadvertently removed their permission to use the input filter or has changed the input filter to something the author does not have permission to use.
It can also help prevent the commonly asked question, "Where has my edit tab gone?"
How it works
This modules directly updates the format column of the node_revisions table. It enables users with the 'administer input formats updater' permission to select a format to update, it also allows further control over which content will be updated giving a choice to filter by a particular user or role.
An additional option, 'Perform access check' ensures that formats are not updated if the author of the node does not have permission to use the new format, uncheck to 'force' formats to be updated regardless.
This module has only been tested with PHP 5 and MySQL.
