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.
Schema Markup Generator
Schema Markup Generator creates JSON-LD schema markup from page or business details entered in a browser. Its homepage lists 23 schema types, including Organization, Product, FAQ Page, Article, Recipe, Event, Job Posting, and Legal Service. Graph mode can combine multiple schema types on one page and connect them through @id. The generated code can be copied into the page it describes; product guidance covers adding it to WordPress with WPCode or plugins such as Yoast and Rank Math, or pasting it into static-site HTML. The tool runs in the browser and requires no signup. Its homepage links to the Schema.org Validator for syntax checks and Google's Rich Results Test for eligibility, and validation and rich-result preview are listed features. The maker presents it for common website content and industry-specific uses such as law firms, e-commerce, hiring, restaurants, and healthcare. Josh Blackburn built the tool and advises marking up only content genuinely visible on the page and using genuine reviews for ratings. One stated constraint is that Service markup is not a standalone rich-result type. The Free plan is listed at free.
