How to use the JSON Schema Library – step-by-step guide

Browse reusable JSON Schema templates for common payloads (users, products, API responses), then generate mock JSON, validate contracts, and turn stable examples into typed code.

  1. Step 1 – Search by use case

    • Use the search box to find templates by name, tags, or scenario (e.g. “user profile”, “pagination”, “product catalog”).
    • Filter by category, complexity, and tags to narrow results quickly.

  2. Step 2 – Preview and evaluate schema structure

    • Open a schema and check key fields, required properties, formats, and constraints.
    • Pick a template that matches your API contract shape (not just the domain name).

  3. Step 3 – Copy or download

    • Copy the schema into your repo to version it alongside API code and docs.
    • Download as a .json file for sharing or tooling.

  4. Step 4 – Generate mock data and fixtures

    • Open the Mock Data Generator to produce realistic sample JSON for tests and demos.
    • Use seed + locale to make data reproducible across environments.

  5. Step 5 – Validate and generate code

    • Validate real payloads against your schema during development.
    • Generate TypeScript/Java/etc. from stable JSON examples to keep clients and servers aligned.

Important note about JSON Schema features

  • Some schemas rely on advanced keywords like $ref, anyOf, oneOf, and allOf.
  • Different validators support different drafts and keywords; run a full JSON Schema validator in CI for strict contract testing.
Example: schema template → mock JSON workflow
// 1) Pick a schema template (user-profile, product-catalog, etc.)
// 2) Open Mock Generator and configure locale + seed + batch size
// 3) Download mock-data.json and use it as a fixture

Frequently Asked Questions

What are JSON Schema templates?

JSON Schema templates are pre-defined schema structures for common data types like user profiles, products, API responses, and more. They serve as starting points for your own schemas or for generating mock data.

How can I use these schemas?

You can view any schema in detail, copy it to your clipboard, download it as a JSON file, or use it directly in the Mock Data Generator to create sample data that matches the schema structure.

What do the complexity levels mean?

Simple schemas have basic properties and shallow nesting. Medium schemas include nested objects and arrays. Complex schemas have deep nesting, multiple relationships, and advanced constraints.

Can I modify these templates?

These are read-only templates, but you can copy them and modify the JSON Schema as needed for your specific use case. The templates serve as excellent starting points for custom schemas.

How do I search for specific schemas?

Use the search bar to find schemas by name, description, tags, or use case. You can also filter by category, complexity level, or specific tags to narrow down the results.

What categories are available?

The library includes schemas for User Management, E-commerce, API responses, Configuration, Financial transactions, Social media, and more. Each category contains schemas relevant to that domain.

How do I generate mock data from a template?

Click the Generate action for any template to open the Mock Data Generator with the schema prefilled. You can then configure record count and options to instantly produce realistic sample data.

Which JSON Schema drafts are these templates compatible with?

Templates follow broadly compatible JSON Schema conventions and are designed as practical starting points. They do not target a strict draft version and may omit advanced keywords; adjust as needed for your tooling.

How do I quickly find the right template?

Use the search box to match name, description, tags, or use cases. Combine Category, Complexity, and Tags filters, then sort by name, category, complexity, or newest to refine results.
