JSON-LD Extractor
Enter a URL to extract every JSON-LD block from its HTML, shown separately with its type and validity.
About this tool
This extracts and pretty-prints each block as-is — for a broader check that also covers microdata and common schema issues, use the Schema Markup Checker.
Frequently Asked Questions
- What does this extract?
- Every <script type="application/ld+json"> block on a page, shown separately with its type and validity.
- Does this validate against schema.org's vocabulary?
- No, for that use the Schema Markup Checker, which covers common schema issues more broadly.
- What if a block has invalid JSON?
- It's shown with its parse error — one malformed block never hides the others.
