How it works

Paste or type your text in the box and JSONL to CSV transforms it instantly — no button to press. The result updates live as you edit, runs entirely in your browser, and you can copy the output with one click.

Examples

  • “{"name":"Ada","age":36} ⏎ {"name":"Bob","age":5}” → “name,age ⏎ Ada,36 ⏎ Bob,5”
