Frequently Asked Questions
How do I convert JSON Lines to a JSON array?
Paste valid JSONL into the input box, run the converter, and copy or download the JSON array output.
What counts as valid JSONL?
Each non-empty line must be valid JSON. The converter reads one JSON value per line and wraps the results in a JSON array.
Will blank lines break the converter?
No. Empty lines are ignored, but invalid JSON on any non-empty line returns an error.
