JSONL to JSON Converter
Convert JSONL (JSON Lines / NDJSON) streams into a single JSON array, with one object per log entry or record.
Every JSONL line becomes one element of the resulting JSON array.
All conversion happens locally in your browser using modern canvas APIs — files never leave your device.
