JSONL to JSON Converter

Paste JSON Lines or NDJSON and get one formatted JSON array. Each line becomes one item, and blank lines are skipped.

Example

Input
{"id":1,"event":"signup","user":"ada"}
{"id":2,"event":"login","user":"alan"}
{"id":3,"event":"purchase","user":"ada","amount":49.5}
Output
[
  {
    "id": 1,
    "event": "signup",
    "user": "ada"
  },
  {
    "id": 2,
    "event": "login",
    "user": "alan"
  },
  {
    "id": 3,
    "event": "purchase",
    "user": "ada",
    "amount": 49.5
  }
]
