In their own words
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.
