}About This Tool
The JSON Structured Schema Lint Space is an advanced validation workbench designed for software engineers, backend developers, and prompt engineers working with structured LLM outputs, function calling schemas, and complex API configuration objects.
Modern LLM platforms like OpenAI (response_format: { type: "json_schema" }), Anthropic Claude, and Google Gemini require strict JSON schemas to guarantee deterministic outputs. This tool validates JSON instance data against Draft-07 / 2020-12 schemas in real time, pinpoints structural path errors, auto-repairs JSON syntax mistakes, infers typed schemas from raw data, and exports clean TypeScript interfaces.
How to Use
- Load Preset or Paste Input: Select a sample preset (OpenAI Structured Output or LLM Function Call Tool) or paste your own JSON Schema and JSON Instance Data.
- Real-Time Structural Validation: The engine instantly highlights whether your data matches your schema. If violations exist, exact error paths and messages appear in the violation report.
- Infer Schema from Data: Click Infer Schema from Data to generate a complete typed JSON Schema automatically from any raw JSON payload.
- Auto-Repair & Format: Click Format JSON to clean single quotes, trailing commas, and formatting errors.
- Export TypeScript Types: Copy the generated TypeScript interface code for immediate backend or frontend integration.
