What is JSON Schema?
JSON Schema is a declarative language for describing and validating the structure of JSON data. It defines what fields are expected, their types, which are required, and how nested objects and arrays are structured. This tool automatically infers a draft-07 JSON Schema from any JSON input — paste your data and get a schema instantly.
Use cases include API documentation, form validation, configuration file validation, and code generation. All processing runs in your browser — your data never leaves your machine.
