Frequently Asked Questions
What is the difference between JSON and JSONL?
JSONL stores one JSON object per line, while JSON array stores all objects inside one array structure.
Can this convert NDJSON?
Yes. NDJSON is line-delimited JSON and is compatible with JSONL conversion here.
Why does conversion fail on some lines?
Any invalid JSON line causes parsing errors. Make sure each non-empty line is valid JSON.
