JSON-LD Generator

What it is

JSON-LD Generator is a free web tool for building structured data markup by filling in fields and viewing the generated code in real time. It supports 17 schema types, including Article, Breadcrumb, Book, Course, Event, FAQ, HowTo, Job Posting, Local Business, Organization, Person, Product, Recipe, Review, Video, WebSite, and WebPage. Product fields include offers, ratings, and reviews; Local Business has more than 100 subtypes, including 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. You can copy the code or open shortcuts to Google's Rich Results Test and the schema.org Validator. Form state is preserved between visits. A companion tool converts addresses to latitude and longitude 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 developers and SEO practitioners learning JSON-LD.
