Schema Markup Generator, JSON-LD Structured Data for Rich Results
Pick a schema.org type, fill a tailored form, and get valid JSON-LD structured data instantly. We validate the required and recommended properties Google needs for rich results, then hand you the exact <script> tag to paste, all in your browser, nothing uploaded.
What is the schema markup generator?
The Schema Markup Generator is a hub for JSON-LD structured data across twelve schema.org types, Article, FAQPage, Product, Organization, LocalBusiness, Event and more, rendering a tailored form per type and validating required and recommended properties for rich results. Free and browser-based, so product prices and event details stay on your device.
The GigAI Schema Markup Generator is the single hub for building schema.org structured data as JSON-LD, the format Google explicitly recommends. Choose a type: Article, FAQPage, Product, Organization, LocalBusiness, Event, BreadcrumbList, VideoObject, Recipe, Person, Review or SoftwareApplication, and the tool renders a form tailored to exactly that type's fields, then emits clean, minifiable JSON-LD live as you type. What sets it apart from generic schema builders is the built-in validity check: every property is graded against schema.org's required and recommended sets for that type, so you can see at a glance whether your markup is eligible for a rich result and precisely which fields are still missing. Empty fields are stripped automatically, dates are handled correctly, and enum shorthands like 'InStock' are expanded to full schema.org URLs. When you're done, copy the ready-to-paste `<script type="application/ld+json">` block or download the raw JSON, and share a link that reopens the tool with your data pre-filled. Because generation and validation happen entirely on your device using the browser's own JSON engine, your product prices, event details, author names and organization data never leave your machine. There is nothing for us to store, log or see.

How to use the schema markup generator
- 1
Choose a schema type
Pick the schema.org @type that matches your page, Article, FAQPage, Product, LocalBusiness, Event and so on. The form rebuilds itself for that type's fields.
- 2
Fill the tailored form
Enter your content. Load a preset first if you want a realistic starting point, then edit the fields, the JSON-LD updates live on every change.
- 3
Read the validity check
Watch the required/recommended report: green means valid, warnings point to recommended fields that improve rich-result eligibility, and errors flag anything mandatory that's still missing.
- 4
Copy the script tag & paste it
Copy the `<script type="application/ld+json">` block (or download the JSON) and paste it into the `<head>` or body of the page it describes.
- 5
Test in Google's Rich Results Test
Paste the same markup into Google's Rich Results Test or Schema Markup Validator to confirm eligibility on Google's own live checker before publishing.
What Schema Markup Generator includes
One hub, twelve schema types
Switch between Article, FAQ, Product, Organization, LocalBusiness, Event, Breadcrumb, Video, Recipe, Person, Review and Software from a single dropdown: each with a form built for exactly that type's fields.
Live rich-results validity check
Every field is graded against schema.org's required and recommended properties, so you instantly see whether your markup qualifies for a Google rich result and what is still missing.
Live JSON-LD as you type
The output pane regenerates on every keystroke with empty fields stripped, dates normalised and enum shorthands like 'InStock' expanded to full schema.org URLs.
Copy the exact script tag
Get a ready-to-paste `<script type="application/ld+json">` block, or download the raw JSON. No hand-editing braces, no guessing where it goes in the page.
Presets, undo/redo & share links
Load a realistic example for any type, undo and redo every edit, and share a link that reopens the generator with your data pre-filled for a colleague.
100% in your browser
Markup is built with the browser's native JSON engine on your device. Prices, event details, author and organization data are never uploaded, stored or logged.
Why use our schema markup generator
Win rich results without hand-writing JSON
FAQ accordions, product star ratings, breadcrumbs, event dates and recipe cards all depend on correct structured data. The generator produces it cleanly so you skip the syntax errors that silently disqualify a page.
Know your markup is valid before you ship
The inline check flags missing required properties as errors and missing recommended ones as warnings, so you fix eligibility problems in the tool instead of discovering them later in Search Console.
Standardise schema across a whole site
Share a pre-filled link or a downloaded snippet so every author emits the same Organization, LocalBusiness or Article shape. Consistent markup Google can trust.
Safe for private business data
Because everything runs locally, you can build markup containing unpublished prices, internal event details or personal author information without any of it leaving your machine.

Hit a snag? Here are quick fixes for the issues people run into most.
The validity check shows an error for a required field.
That property is mandatory for the type. E.g. an Article needs a headline, an Event needs a name and startDate. Fill it in and the error clears. Errors mean the markup is not yet eligible for that rich result.
It says a recommended property is missing (a warning).
Warnings never block validity, but recommended fields (like a Product image or an Article author) materially improve rich-result eligibility. Add them where you can: Google favours complete markup.
My availability or event status looks like a plain word.
Enter shorthands like 'InStock' or 'EventScheduled' and the generator expands them to the full schema.org URL Google expects. You can also paste the full https://schema.org/… value directly.
Google's test flags an issue my tool didn't.
This tool is a pragmatic linter for required/recommended properties, not a full schema.org shape validator. Always confirm with Google's Rich Results Test before publishing. It checks Google-specific eligibility rules on top of valid JSON-LD.
Get the most out of it
JSON-LD in a `<script>` tag is Google's recommended format, prefer it over Microdata or RDFa, and you don't have to touch your visible HTML.
One page can carry multiple schema blocks: add separate Organization, BreadcrumbList and Article scripts rather than forcing everything into one object.
Only mark up content that's actually visible on the page. Invisible or mismatched structured data can trigger a manual action.
Load a preset to see a fully-populated, valid example of any type, then swap in your own values field by field.
After copying, always run the markup through Google's Rich Results Test. Passing this tool's check is necessary but Google adds its own eligibility rules.
