Schema Extractor

Extract and validate the JSON-LD structured data a page actually serves.

Free · instant

Run a deterministic technical check

The result comes from HTTP requests, parsers and maintained rules — no AI guessing, so it is reproducible.

A specific public page, e.g. https://yourbrand.com/guides/one

Requests are rate-limited and cached. Only public content is fetched.

01

What does this tool check?

We pull every application/ld+json block from the raw HTML, parse it (including @graph nesting), list the schema.org types found, and surface JSON errors that silently disable the whole block.

02

How should I read the result?

One trailing comma invalidates an entire JSON-LD block — parsers do not partially accept it. Types shown are what the page serves, which is not a promise that any engine uses them.

03

What should I do next?

Fix parse errors first, then make sure the types match the page content (FAQPage on a FAQ, Product on a product).
