JSON-LD Generator vs SchemaValid

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.

SchemaValid is a browser-based toolkit for JSON-LD, structured data and technical SEO. Its tools include schema validation, sitemap and robots.txt utilities, plus tools for text and content, AI search, analytics, campaigns and other tasks such as IBAN validation. The validator checks a live URL or pasted JSON-LD and reports an SEO score, errors, warnings and rich-results readiness. URL checks provide scorecards for 16 schema types, including Organization, Product, Article, Recipe, Event, FAQPage, JobPosting, Course, VideoObject and SoftwareApplication; the limit is five URL checks per minute per visitor. Pasted-code validation runs locally without uploading or storing the code or tying it to an account. The AI Search Readiness Checker scores a page out of 100 across eight categories, using the page and its robots.txt, sitemap.xml and llms.txt. A robots.txt editor offers a live preview for crawler rules, AI-bot access and sitemap settings. The tools are free without registration, though availability may change.
