SharePoint Item Permission Batch is used to modify all items permissions in a SharePoint list.
In a SharePoint list, each item has been assigned unique permission,if SharePoint user needs to add/remove some permission, with default SharePoint permission setting, it is quite a tedious task to set item permisison one by one.
With SharePoint Item Permission Batch, it is possible to add or remove permissions to users/groups or user/group field columns for all items. The user/group field column are columns which represent users/groups, including "Created By", "Modified By" etc. inner columns and other users/groups columns such as "Manager".
