JSON Schema Validator (Private & Secure)

Validate JSON data against JSON Schema specs entirely in your browser using AJV. Free, private, and fast.

  2. Paste your JSON Schema in the right editor.
  3. Validation runs as you type and lists each violation with its JSON path.

Technical Considerations

  • External $ref URLs are not fetched; only local refs (#/definitions/...) resolve.
