About this tool
Parses pasted JSON, or the first matching JSON-LD script block, and reports basic @context, @type and selected top-level property-presence hints. It follows arrays and @graph for those hints. It does not expand JSON-LD contexts, verify vocabulary terms or property values, inspect a live URL, or establish Google rich-result eligibility.
Review the generated values before publication. JSON serialization alone does not establish vocabulary correctness or search-feature eligibility.
