Line-preserving validationL✓
Ready to validateEach non-empty line is parsed and validated independently against the same schema.
Useful for generated datasets and batch outputs
The validator preserves JSONL line numbers, making failed records easy to locate. A pass only covers the JSON Schema keywords implemented by this browser validator; unsupported keywords are surfaced explicitly.
