Frequently Asked Questions
What is JSONL?
JSON Lines: a text format where each line is an independent and valid JSON object. Preferred for large datasets and AI training files (e.g., fine-tuning) because it can be processed line by line.
What are the headers when converting from CSV?
The first line is accepted as field names; each data line is converted into a JSON object in the format {"header": value}. Numerically appearing values are written as numbers.
