What is JSONL format?

JSONL (JSON Lines) is a format where each line contains a valid JSON object. It is commonly used for data streaming, log files, and training datasets for machine learning.

How does CSV to JSONL conversion work?

The tool reads your CSV file, treats the first row as headers, and converts each subsequent row into a JSON object. Each object is written on its own line in the output file.

Why use JSONL instead of regular JSON?

JSONL is better for streaming and large datasets because each line can be processed independently without loading the entire file into memory.

Is the conversion done locally?

Yes, all processing happens in your browser. No data is uploaded to any server.
