## Overview (en)

JSON-LD Schema Generator creates a Schema.org structured-data object for an Article, Event, Organization or Product from the fields you fill in. Every type gets name, url and description; Articles add headline, datePublished and a Person author, Events add startDate and a Place location, and Organizations add an address. The canonical URL must be a valid URL.

## Questions (en)

### How do I add the generated JSON-LD to my web page?

Copy the JSON or download structured-data.json, then place it inside a script element with the type application/ld+json in your page. The tool outputs only the JSON object, not the surrounding script tag.

### Will this JSON-LD make my page eligible for rich results?

Not by itself. The output is a basic Schema.org draft with a small set of properties, and rich-result eligibility has additional requirements. Validate the markup separately with a structured data testing tool before publishing.

### What date format should I use for Article or Event schema?

Enter dates in ISO 8601 format, such as 2026-09-29. For an Article the value becomes datePublished, and for an Event it becomes startDate. The date is inserted as typed without validation, so check it carefully.
