LOCAL STRUCTURED DATA CHECK
Inspect JSON-LD blocks
JSON-LD inspection guide
Extract JSON-LD structured-data blocks from HTML, validate their JSON, and inspect the declared Schema.org types.
The analysis is local and does not submit your page or data anywhere.
JSON-LD syntax versus Schema.org meaning
Valid JSON-LD only proves that the block is parseable JSON. It does not prove that required properties are present, that a type is eligible for a rich result, or that the values describe the page accurately.
Multiple blocks deserve review
A page may contain several structured-data blocks or an @graph. Inspect the types together and watch for repeated or conflicting representations of the same entity.
Use the right validator for the final check
This tool is a fast local inspection aid. Use the relevant search-engine testing tool and Schema.org documentation when rich-result eligibility or vocabulary compliance matters.
Frequently asked questions
Can I paste raw JSON-LD?
Yes. You can paste a JSON object or array, or HTML containing application/ld+json script blocks.
Does this check rich-result eligibility?
No. It checks JSON syntax and shows types; eligibility needs a dedicated search-engine test.
Does it upload my HTML?
No. Parsing runs entirely in your browser.
Privacy note: JSON-LD parsing happens in your browser. Your HTML and structured data are not stored or uploaded.
