About
Sellers.json Inspector is a browser extension designed to parse, visualize, and validate sellers.json and buyers.json inventory metadata. It transforms raw JSON pages into an interactive, syntax-highlighted interface for fast, in-page inspection and verification. Key Features: • Real-time syntax highlighting for raw JSON documents directly in the browser. • Interactive overview panel displaying domain-level and seller-level aggregate statistics. • Remote parallel validation of seller IDs against the publisher's ads.txt and app-ads.txt files. • Validation pre-filtering for malformed or missing seller domains. • Customizable JSON token colors (keys, strings, numbers, booleans) and toggles for statistical counters via the extension popup. • Export tools to copy filtered JSON subsets to the clipboard or save them as .json files. This tool is built for ad-ops professionals, SSPs, and QA teams requiring a reliable, privacy-friendly workflow for programmatic supply-path verification.
