Frequently asked questions
What does the JSON-LD visualizer do?+
It parses your structured data into an expandable tree so you can see the entity hierarchy at a glance, and renders a preview of how eligible types (Product, Article, FAQ, Breadcrumb) can appear in search and AI answers.
How is a visualizer different from a validator?+
The validator tells you whether your markup is correct and rich-result eligible. The visualizer helps you understand the structure — nested objects, @type hierarchy, and how the data maps to a search appearance — which is useful when debugging complex or nested schema.
Does it work with nested and @graph schema?+
Yes. It walks nested objects, arrays, and @graph collections, so multi-entity markup (for example a WebPage that contains an Article and a BreadcrumbList) renders as a full tree.
Is it free and private?+
Yes — free, no signup, and fully client-side. Your markup never leaves the browser.
