What BlueGrid Schema Validator is

BlueGrid Schema Validator is a free web tool for building JSON-LD schema markup and checking 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. The JSON-LD output updates as the form is filled in and can be copied with a script-tag wrapper.

For validation, it checks JSON syntax, @context and @type, required and recommended properties, and common value formats such as dates, URLs, and prices. When properties are missing, the tool can return revised JSON-LD with placeholders and a completeness score. Users can also submit a page URL so its JSON-LD can be fetched through a public proxy and analyzed in the browser. The maker says pasted JSON-LD is validated in the browser and generated content is not uploaded. Rich-result checks cover types including Article, Product, Offer, FAQPage, HowTo, LocalBusiness, Recipe, VideoObject, JobPosting, and Service. Rich-result preview is included; results can 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 show one.

Who it suits

It suits people who need to generate JSON-LD for supported content types or check markup already on a page. It may also help site owners review rich-result requirements and share or embed validation results.
