In their own words
Google Rich Results Test
Google Rich Results Test is a free web tool for checking structured data and identifying rich result types a page may enable in Google Search. You can enter a full URL or paste code, then rerun the test. It accepts JSON-LD, RDFa, and Microdata, and can render JavaScript. Testing uses either a smartphone or desktop user agent, with smartphone selected by default. Results report structured-data errors and suggestions, identify detected result types, and show relevant rendered source code in an explorer. Some types receive previews for possible Search or Google Assistant appearances, including desktop and mobile layouts where available. Results can be shared through browser links without permissions; test state and code are saved, while shared links and bookmarked history remain available for approximately 90 days. Anonymous testing needs no Search Console permission, but pages and resources must be reachable publicly. A tunnel can expose local or firewalled pages. Preview output is not guaranteed to match the eventual Search result.
JSON-LD Generator
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.
