See the schema.org structured data (JSON-LD and microdata) on any page in one click. Free tool from Yellowfin Development.

Most schema checkers make you copy a URL into a separate site, wait for it to load, then dig through a wall of results to find out what is actually on the page. Schema Inspector skips that step. Click the icon and it reads the JSON-LD and microdata already sitting in the page you are looking at: what entities are declared, what type each one is, and whether the JSON is even valid. Grouped, readable, and copyable in one click. Built for anyone who works with SEO or web development day to day - checking your own markup before it ships, auditing a client's site, or just curious what a page is telling Google about itself. Everything happens locally in your browser. Nothing is collected, stored, or sent anywhere. Built by Yellowfin Development, a web design and SEO company on Long Island, NY. yfdev.com Common questions What's the difference between JSON-LD and microdata? Both are ways to add schema.org structured data to a page. JSON-LD sits in a single script tag, separate from the visible HTML. Microdata is spread across attributes on the actual elements. Google reads both the same way. Schema Inspector detects both. Does this replace Google's Rich Results Test? No. Rich Results Test validates your markup against Google's specific eligibility rules. Schema Inspector just shows you what's actually on the page, instantly, without leaving the tab. Different job, useful for different moments. Does it work on any website? Yes, any page you can view in Chrome. It only reads the page you're actively on, and only for the second you click the icon. Is my data safe? Nothing is collected, logged, or sent anywhere. Everything happens in your browser.
