- 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.
- The enclosing array is removed; each element remains a complete JSON value. Newlines inside strings stay escaped.
- An empty array produces an empty file. No trailing blank line is added.
