JSON-LD Generator (schema.org structured data)

Build valid schema.org JSON-LD for Article, Product, FAQ, Breadcrumb and more — with the exact tag to paste, and a warning for each mistake that costs you the rich result.

Schema type Page URL (absolute — this is what Google needs)

Headline Description Date published Author name Image URL

Site name Description Language

Product name Description Price (digits only) Currency (ISO 4217) Availability Brand Image URL

Organization name Description Logo URL Same-as profiles (space or comma separated)

One level per line: Label | /path

One pair per line: Question | Answer

JSON-LD, then the exact tag to paste

How to use

Pick a schema type, fill the field that matter for that type, and put in the absolute URL of the page. The generator writes the JSON-LD for you, then shows the exact script tag to paste into the head of that page. Anything that would make Google drop the rich result is listed as a warning above the output, so you fix it before shipping rather than after.

FAQ

It does not need a network call: the object is assembled and validated in the browser, so nothing you type is uploaded. The warnings encode the rules that actually decide eligibility — an Article without an image cannot show a large card, a Product without offers cannot show a price, price must be digits with no currency symbol, and priceCurrency must be a three-letter ISO code. Breadcrumb and FAQ take one 'Label | /path' or 'Question | Answer' pair per line, and an absolute page URL is required because Google resolves mainEntityOfPage and offers.url against it.
