Show Data Variables is a robust browser extension designed to enhance data inspection capabilities within Chrome. This tool allows users to discover, organize, and inspect hidden or non-obvious data across the Document Object Model (DOM), storage, and runtime JavaScript. With its ability to scan 11 data categories such as cookies, localStorage, and meta tags, it streamlines the debugging process, making it ideal for QA, reverse engineering, and privacy reviews.

The extension features a clean, drill-down user interface that presents results efficiently. Users can benefit from immediate feedback through a live re-scan mode that detects changes in real time, leveraging a DOM MutationObserver. Additionally, it allows for in-place editing of data values, enabling users to test hypotheses directly on the page. Comprehensive analytics and export options to CSV further enhance its utility for reporting and audits.
