QS Metadata Explorer is a free Chrome extension aimed at Qlik Sense developers, analysts, and administrators. It facilitates the understanding, auditing, and optimization of Qlik Sense applications by integrating seamlessly with existing sessions using the Enigma.js library. This ensures that all operations remain local to the user's browser, thereby maintaining data privacy without relying on external services. Users can explore and manage various metadata types including scripts, data models, sheets, visualizations, and more, with options to export data directly to Excel and capture screenshots of sheets for reporting purposes.

In addition to metadata management, QS Metadata Explorer offers application optimization features, providing hints for improving performance by detecting issues like synthetic keys and circular references. It includes a function catalogue with reusable Qlik load scripts and expressions to streamline development. Security is prioritized as the extension operates entirely client-side, utilizing the user's existing authenticated Qlik Sense session without any external communication. This tool is community-driven, free to use, and designed to enhance the Qlik Sense development experience.
