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.
SEO Schema Markup
SEO Schema Markup is a free browser toolkit for generating schema.org JSON-LD and validating markup against Google requirements. Generators cover FAQ, Product, Shopify Product, Article and Author, Local Business, Organization, Breadcrumb, Event, and Review and Rating schema. Each generator provides live validation, one-click copying, and a script snippet ready to paste. The validator accepts JSON-LD or HTML and identifies missing required and recommended properties, linking issues to the matching generator. The Shopify Product generator creates dynamic Liquid markup that fills product title, price, variants, and ratings. The site describes adding generated code to HTML, WordPress, Shopify, or a Google Tag Manager Custom HTML tag. It recommends Google's Rich Results Test for final eligibility checks. The tools run in the browser, and the site says markup is never uploaded. The project is open source under the MIT license and requires no signup. WebSensePro built the project, with Bilal Naseer identified as maker. The site also publishes schema guides and blog posts and links to a YouTube channel.
