The EndNote Style (ENS) format is a proprietary configuration file developed by Clarivate for the EndNote reference management system. It enables researchers and academics to automate the formatting of bibliographies and in-text citations according to specific journal guidelines or institutional standards. As a passive data format containing formatting logic rather than executable instructions, ENS files are considered safe and represent a negligible security risk when shared between users or systems.
