- If a line fails, correct the reported line and convert again.
What to know about the result
- Processing stays in this browser. Inputs are never executed and no data is sent to an API.
- Inputs are limited to 200,000 characters, 64 nesting levels, and 50,000 JSON values. Quote integers outside the safe integer range.
- LF and CRLF line endings are supported, and blank lines are skipped. JSON strings containing line breaks must use escaped \n.
- Objects, arrays, scalars, and null are all allowed as individual JSON Lines values.
