JSON-LD Schema Generator
A JSON-LD schema generator turns your page's details into the structured data markup search engines use to build rich results — star ratings, FAQ dropdowns, business info panels. Pick a schema type, fill in the fields, and copy a ready-to-paste <script type="application/ld+json"> tag. Everything runs in your browser — nothing is sent to a server.

What is JSON-LD structured data?
JSON-LD (JavaScript Object Notation for Linked Data) is the format Google recommends for structured data. It's a small block of code, separate from your visible page content, that describes what a page is about in a way search engines and AI systems can read directly — instead of inferring it from headings and paragraphs. It's what powers rich results: star ratings under product listings, FAQ dropdowns in search results, and business info panels in Google's Knowledge Panel.
Google, Bing, and AI answer engines like ChatGPT and Perplexity all parse JSON-LD when they crawl a page. Getting the fields right matters — a single typo or missing required property can mean a rich result never shows up, or worse, Search Console flags the page with a structured data error. It pairs naturally with the Meta / OG Tag Generator — structured data and meta tags cover different rich-result and social-share surfaces, but both come from the same page details.
For example, filling in just a name and URL for the Organization type produces:
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Frost Rank",
"url": "https://frostrank.com"
}How to use this tool
-
1
Choose a schema type
Pick Organization, Person, Product, Article, Local Business or FAQ Page, matching what the page is actually about.
-
2
Fill in the required fields
Each type marks its required fields. The code appears as soon as they are filled in and updates with every change.
-
3
Add optional detail
Add a logo, social profiles, price, author, address or opening hours where relevant. For an FAQ page, use "+ Add question" for each question and answer.
-
4
Copy the code
Click "Copy code" to copy the complete script block, ready to paste.
-
5
Add it to the page and test it
Paste it into the page's HTML, publish, then run the live URL through Google's Rich Results Test to confirm it is read correctly.
Common use cases
- Adding Organization markup to a homepage so search engines connect your name, logo and social profiles to one entity.
- Marking up a product page with price, currency, availability and brand.
- Giving blog posts Article markup with a headline, author and publish and modified dates.
- Describing a local business's address, phone number and opening hours for local search.
- Turning an FAQ section that is already on the page into FAQPage markup.
Tips and common mistakes
- Only mark up what visitors can see. Structured data that describes content missing from the page, such as ratings with no visible reviews, breaks Google's guidelines and can lead to a manual action.
- Keep one consistent identity. Use the same organization name, URL and logo on every page rather than slightly different versions that look like separate businesses.
- Hand edits break easily. If you change the generated code yourself, run it through the JSON Formatter & Validator to catch a stray comma, then fetch the live page with the HTML Formatter & Source Checker to confirm the script actually made it into the published HTML.
- Markup is not a guarantee. Valid schema makes a page eligible for rich results, but Google decides whether to show them. The JSON-LD structured data guide covers which types are worth the effort.
Frequently asked questions
JSON-LD is a way to add structured data to a page: one script block of type application/ld+json that describes the page's entities, such as an organization, product or article, using the schema.org vocabulary. It sits apart from the visible HTML, which is why Google recommends it over Microdata and RDFa, and it's the format this tool generates. Read the complete JSON-LD structured data guide.
JSON-LD stands for JavaScript Object Notation for Linked Data. It's ordinary JSON plus a few reserved keywords, such as @context, @type and @id, that tie each value to a shared vocabulary and let one entity reference another. It's a W3C Recommendation, first published as version 1.0 in 2014 and updated to version 1.1 in 2020. See how JSON-LD works in practice.
Organization, Person, Product, Article, Local Business, and FAQ Page — the six types most commonly used for standard business, portfolio, e-commerce, and content sites.
Most sites place it in the <head>, but Google accepts JSON-LD anywhere in the HTML — <head> or <body> both work. What matters is that it's valid JSON and present somewhere on the rendered page.
It's good practice. This tool generates spec-compliant JSON-LD, but we'd still recommend running the final page through Google's Rich Results Test to confirm eligibility for the specific rich result you're targeting.
No tool can guarantee that — valid structured data makes your page eligible, but Google decides whether and when to show a rich result based on many factors, including overall page quality.
Yes, completely free with no signup. Everything runs in your browser — the fields you fill in are never sent to a server.
This generator follows the current schema.org vocabulary and Google's structured data guidelines — built after years of debugging real Rich Results errors in Search Console, not just reading the spec docs. Every output is checked against the exact fields Google's own Rich Results Test expects for each type.
