Generated JSON Schema

How It Works

  1. Paste JSON: Enter your example JSON data into the "JSON Input" area. You can also load a sample.
  2. Choose Method:
    • **Basic:** Use the client-side generator. Adjust options like "Allow Null Types" or "Mark Top-Level Required" via the Options button.
    • **AI Enhance:** Toggle the AI Enhance switch. This will use AI to generate a more detailed schema (may infer formats, descriptions, examples). Basic options are ignored in AI mode.
  3. Generate: Click the "Generate Schema" button.
  4. Review & Use: The generated JSON Schema will appear in the output area. Copy it for use in your projects for validation, documentation, or code generation.

Features & Benefits

Schema Generation

  • ✓ Infers types (string, number, boolean, object, array, null).
  • ✓ Handles nested objects and arrays.
  • ✓ Basic inference for array item types.
  • ✓ Options for null types and required fields (basic mode).

AI Enhancement (Optional)

  • ✓ Attempts to infer string formats (date-time, email, etc.).
  • ✓ Generates basic property descriptions.
  • ✓ Includes examples based on input data.
  • ✓ Potentially more accurate type inference (e.g., integer vs number).

Use Cases

  • ✓ Data validation (API inputs/outputs).
  • ✓ Generating documentation for data structures.
  • ✓ Input for code generation tools (e.g., types from schema).
  • ✓ Defining configuration file structures.

User Experience

  • ✓ Simple copy-paste interface.
  • ✓ Clear separation of input and output.
  • ✓ Options easily accessible via popover.
  • ✓ AI enhancement toggle for flexibility.
