BlueGrid Schema Validator vs JSON-LD Generator

BlueGrid Schema Validator is a web tool for generating JSON-LD markup and checking it against schema.org vocabulary and Google rich-result requirements. Its form-based generator builds markup for types including LocalBusiness and trade subtypes, Organization, Person, Service, FAQPage, Article, BlogPosting, NewsArticle, Product, BreadcrumbList, Event, and Review. The output updates as the form is completed and can be copied inside a script-tag wrapper. For validation, it checks JSON syntax, @context and @type, required and recommended properties, and common formats such as dates, URLs, and prices. Missing properties can lead to corrected JSON-LD with placeholders and a completeness score. Users can also submit a page URL for its JSON-LD to be 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 included, and results can be shared by link or the validator embedded on another site. The maker cautions that valid markup can qualify a page for rich results but cannot ensure Google displays one.

JSON-LD Generator is a free web tool that creates structured data markup from fields users fill in, with generated JSON-LD shown in real time. It covers 17 schema types, including Article, Breadcrumb, Course, Event, FAQ, HowTo, Local Business, Organization, Product, Recipe, Review, Video, WebSite and WebPage. Product fields include offers, ratings and reviews; Local Business offers more than 100 subtypes, with examples such as Restaurant, Hotel and Dentist. The tool displays live checks for required fields and produces JSON using JSON.stringify, which the site describes as strictly valid JSON. Users can copy the generated code and open Google’s Rich Results Test, or follow a shortcut to the schema.org Validator. The form state is preserved between visits. A companion address-to-latitude-and-longitude tool is available for Local Business or Organization data. The generator runs on the web and requires JavaScript. Its creator, Patrick Coombe, says the site launched in 2017 as a reference for web developers and SEO practitioners learning about JSON-LD.
