What this tool does

JSONLines Formatter gives you a fast, focused way to validate and normalize JSONLines so each non-empty line contains one compact JSON value. Everything runs locally in this tab.

The result is produced only after the input is checked. If the value cannot be processed, the workspace reports a specific error instead of guessing.

Example

{ "id": 1, "name": "Ada" }
{ "id": 2, "name": "Grace" }

Limitations

• Review important output before using it in production.
• Very large inputs remain subject to browser memory limits.
