- Use a full implementation or the relevant consumer’s test for complete validation.
About this tool
Parses pasted JSON or matching JSON-LD script blocks, finds nested typed objects, and reports a built-in list of missing-field hints and duplicate @id warnings. These are local heuristics, not full JSON-LD processing, Schema.org validation, current Google eligibility rules or a live-page test. Unknown vocabulary terms and invalid property values can pass these checks.
Review the generated values before publication. JSON serialization alone does not establish vocabulary correctness or search-feature eligibility.
