Convert structured data formats
Supports a documented subset of Schema.org Microdata and simple RDFa; not a full W3C RDFa processor. Pasted HTML is parsed inertly and never executed.

Output
Four supported conversion examples
- Simple Product Microdata: Paste an element with
itemscope,itemtype="https://schema.org/Product"and a nesteditemprop="name". Inspect the JSON-LD type and name; do not assume other Product requirements were supplied. - Simple RDFa Person: Use
typeof="Person"with a name property in a small HTML fragment. Review the resulting entity and check that the property was actually represented in the input. - JSON-LD to HTML: Paste a small JSON-LD object containing an Organization name and URL. Convert to the chosen HTML syntax and inspect the generated attributes before inserting the markup into a page.
- Nested data: Try a Product with an Offer object. Compare the output to the original JSON-LD and identify any nesting the limited converter cannot represent faithfully.
Common mistakes and fixes
Do not treat this as a complete W3C Microdata or RDFa processor: advanced vocabularies, complex prefixes, language tags and graph relationships may not round-trip. Pasted HTML is parsed inertly, not executed, and remote linked data is not fetched. Never overwrite production markup without comparing the original and converted entities. When a field is missing, check the input attributes and the tool's limitation notes rather than inventing values.
Review workflow: Convert a minimal sample, inspect the output, compare entity types and identifiers, then run the final markup through Schema Markup Validator. For format details see the HTML Microdata specification.
