JSON-LD generator

Create JSON-LD structured data wrapped in a <script type="application/ld+json"> tag for schema.org WebSite, Article, or FAQPage types.

Schema types

• WebSite — name, optional URL and description for site-level rich results.
• Article — headline, author, publication date, and URL for editorial content.
• FAQPage — question and answer pairs from Question|Answer lines (one FAQ per row).

When to use it

Add machine-readable context for search rich results, validate FAQ markup before publish, or teach JSON-LD syntax without hand-escaping JSON in HTML.

Limitations

Output is not validated against Google's live rich-result tester. Only the three listed types are supported — no Product, Organization, or BreadcrumbList templates. FAQ lines must use the Question|Answer pipe format.

Example

FAQPage with What is JSON-LD?|A script block search engines read produces valid FAQPage mainEntity JSON inside a script tag.
