One line, one record

Turn plain text into clean JSONL.

Paste arbitrary lines, choose an encoding label, normalize each line to UTF-8 JSONL, and download the result. The browser handles the conversion; process priority and core scheduling stay outside this artifact.

Conversion status

Every non-empty line becomes one JSON object with a line number and text field.

0 lines
Paste text to prepare a JSONL file.

Method, made visible

The original app is C# and multithreaded. This browser version keeps the useful data transformation explicit and honest.

Choose the source label before conversion. Output is UTF-8 JSONL, one object per non-empty input line.
The preview is produced in this browser tab. It does not claim control over operating-system priority or all available cores.
