✅ JSON Schema Validator
Validate JSON data against JSON Schema with field paths, error reasons, and validity status.
No input
Validate JSON data against JSON Schema and get valid / invalid status, field paths, error counts, and detailed reasons. Useful for API contract checks, mock data debugging, and pre-import structure validation. The schema, JSON input, and error details are processed in the current browser and are not uploaded to LittleOne Tools servers. Results should still be reviewed against the real server schema and business rules.
