Frequently Asked Questions
What is JSONL format?
JSONL (JSON Lines) is a format where each line is a complete, valid JSON value. It is commonly used for log files and streaming data.
What input does this tool expect?
A JSON array of objects. Each array element is written as a separate line in the JSONL output.
Is my data uploaded to a server?
No. Conversion runs entirely in your browser using JavaScript.
Example input/output
Input: [{"name":"Ada"},{"name":"Bob"}]
Output: {"name":"Ada"}
{"name":"Bob"}
How it works
This tool parses the JSON array and serialises each element as a compact JSON string on its own line. Processing runs in your browser.
Common use cases
- Convert bulk JSON data to JSONL format for ingestion into log aggregation systems.
- Prepare data files for machine-learning pipelines that consume JSONL.
- Split a JSON array into a streaming-friendly newline-delimited format.
