How to Convert GraphQL to JSON - Step by Step Guide

Step 1

Input Your GraphQL Schema or Query

Start with your GraphQL schema or query. Whether you're working with Apollo Server, need to analyze schema structure, or want to format GraphQL first, you have several options:

•
Paste directly: Copy your GraphQL schema or query and paste into the editor
•
Upload a file: Click "Upload" to select a .graphql or .gql file
•
Try the sample: Click "Sample" to see conversion in action

Example: GraphQL Schema Input

Here's a sample GraphQL schema:

type User {
  id: ID!
  name: String!
  email: String!
  posts: [Post!]!
}

type Post {
  id: ID!
  title: String!
  content: String!
}
Step 2

Automatic Conversion to JSON

The converter automatically transforms your GraphQL to structured JSON:

•
Schema introspection: Extracts all types, fields, and relationships
•
Structured output: Organizes types, fields, arguments, and directives in JSON format
•
Complete metadata: Includes descriptions, deprecation info, and type details

Example: JSON Output

The converted JSON with full schema structure:

{
  "types": [
    {
      "name": "User",
      "fields": [
        { "name": "id", "type": "ID!" }
      ]
    }
  ]
}
Step 3

Review JSON Structure

Examine the generated JSON representation:

•
Valid JSON: Output follows standard JSON format for easy parsing
•
Complete schema: All types, fields, and relationships preserved
•
Analysis ready: Use for documentation, visualization, or schema comparison
Step 4

Export and Use

Save your JSON output for various uses:

•
Copy to clipboard: One-click copy for pasting into your application
•
Download as JSON: Save as .json file for documentation or analysis
•
Schema documentation: Use with visualization tools or generate docs

Frequently Asked Questions

Why convert GraphQL to JSON?

Converting GraphQL schemas to JSON format makes them easier to analyze programmatically, visualize with tools, generate documentation, compare schema versions, or integrate with systems that work with JSON data structures.

What information is included in the JSON output?

The JSON output includes all schema information: type definitions, field names and types, arguments, return types, nullability, descriptions, deprecation notices, directives, and relationships between types. It's a complete representation of your GraphQL schema.

Can I convert GraphQL queries or just schemas?

You can convert both GraphQL schemas and queries. Schemas are converted to a structured type representation, while queries are parsed into their AST (Abstract Syntax Tree) format in JSON, showing the query structure and operations. You can also validate your schema first.

Is this the same as GraphQL introspection?

Yes, it's similar! The converter produces a JSON representation similar to GraphQL's introspection query results, making it compatible with tools that consume introspection data. It's useful for offline schema analysis without needing to query a live GraphQL endpoint.

Can I use the JSON output for documentation generation?

Absolutely! The JSON format is perfect for feeding into documentation generators, schema visualization tools, or custom documentation systems. You can also convert it to other formats like TypeScript or use it with JSON formatting tools.

Is this tool free to use?

Yes, completely free with no limitations on schema size or conversion frequency. No registration required, and you can convert unlimited GraphQL schemas to JSON format.
