BlueGrid Schema Validator
What it is
BlueGrid Schema Validator is a free web tool from Blue Grid Media for generating JSON-LD schema markup and validating existing markup against schema.org vocabulary and Google rich-result requirements. Its form-based generator supports LocalBusiness and trade subtypes, Organization, Person, Service, FAQPage, Article, BlogPosting, NewsArticle, Product, BreadcrumbList, Event, and Review. Output updates live and can be copied with a script-tag wrapper. Validation checks JSON syntax, @context, @type, required and recommended properties, and formats such as dates, URLs, and prices. Missing properties can produce corrected JSON-LD with placeholders and a completeness score. Users may submit a page URL; its JSON-LD is fetched through a public proxy and analyzed in the browser. The maker says pasted markup is validated in the browser and generated content is not uploaded. Results can be shared by link, and the validator can be embedded elsewhere. Rich-result preview is included. Valid markup may make a page eligible for rich results, but does not ensure Google will display one.
For and against
For
- Free plan requires no signup
- Generates JSON-LD from forms
- Checks syntax and required properties
- Provides corrected markup placeholders
- Supports sharing and embedding
Against
- Rich-result eligibility is not guaranteed display
- URL fetching uses a public proxy
- Coverage is limited to listed schema types
The verdict
BlueGrid Schema Validator combines browser-based generation, validation, previews, and correction guidance at no cost. Treat its checks as eligibility assistance rather than a guarantee that Google will show rich results.
Who it suits
BlueGrid Schema Validator suits site owners and developers creating or checking JSON-LD in a browser. It is useful for those working with supported schema types and rich-result requirements.
