Schema Markup Checker
Enter a URL to extract its JSON-LD and microdata structured data, with each JSON-LD block validated independently.
What this checks
This tool fetches the page and extracts every application/ld+json script block, parsing each one independently so a single malformed block never hides the others, plus a check for inline Microdata. This validates that the JSON itself is well-formed — it does not run Google's full Rich Results eligibility checks.
