What BlueGrid Schema Validator is
BlueGrid Schema Validator is a free web tool for generating JSON-LD schema markup and checking existing markup against schema.org vocabulary and Google rich-result requirements. Its form-based generator supports types such as LocalBusiness, Organization, Person, Service, FAQPage, Article, Product, Event, and Review, with additional subtypes including BlogPosting and NewsArticle. The output updates as users fill in the form and can be copied with a script-tag wrapper. Validation checks JSON syntax, @context and @type, required and recommended properties, and common formats such as dates, URLs, and prices. When properties are missing, the tool can supply corrected JSON-LD with placeholders and a completeness score. Users can submit a page URL so 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. Rich-result preview is available; results can also be shared by link, and the validator can be embedded on another site. Valid markup can make a page eligible for rich results, but does not ensure Google will display one.
Good
- Free to use with no signup listed.
- Generates JSON-LD from a form.
- Checks required properties and common value formats.
- Offers corrected markup and a completeness score.
Watch out
- A valid result does not guarantee Google will show rich results.
- Page URL analysis fetches JSON-LD through a public proxy.
Who it suits
It suits site owners and developers creating or reviewing structured data for webpages. The browser-based workflow may also appeal to people who want to avoid uploading pasted markup.
Verdict
BlueGrid Schema Validator combines markup generation with checks for syntax, properties, and rich-result requirements. Treat its eligibility checks as guidance rather than a promise that Google will display a rich result.
