Overview
About Schema Validator
Schema Validator checks JSON-LD structured data for valid JSON syntax and common required fields such as @context and @type. It is useful before publishing FAQ, article, product, breadcrumb or organization schema. This tool catches common issues, but final rich result eligibility should still be checked with official search engine testing tools.
