JSON to JSONL Converter
Convert JSON data to JSON Lines format (one JSON object per line)
How to Use
- 1
Enter or paste your JSON data
Type or paste the JSON array you want to convert into the input field. The tool expects a JSON array of objects.
- 2
Click the 'Convert to JSONL' button
The tool will process your JSON array and convert it to JSON Lines format, with one JSON object per line.
- 3
Review the converted JSONL
The converted JSONL will appear in the output field. Each line will contain a single JSON object.
- 4
Copy or download the result
Use the copy button to copy the JSONL to your clipboard, or download it as a .jsonl file.
Frequently Asked Questions
- What is JSON Lines (JSONL) format?
JSON Lines (JSONL) is a format where each line is a valid JSON object, separated by newlines. It's designed for streaming data processing and is easier to work with for large datasets because you can process one line at a time without loading the entire file into memory.
- Why would I convert JSON to JSONL?
JSONL is useful for data streaming, log files, and processing large datasets. It allows you to process data line by line, which is more memory-efficient than loading an entire JSON array. Many big data tools and platforms like Apache Spark, Elasticsearch, and machine learning frameworks prefer JSONL for data ingestion.
- What kind of JSON can be converted to JSONL?
This converter works best with JSON arrays containing objects. Each object in the array will become a line in the JSONL output. If your JSON is not an array, the converter will attempt to handle it appropriately, but the most common use case is converting arrays of objects.
- Will the converter preserve all my data?
Yes, all data from your JSON objects will be preserved in the conversion. The only change is the format - from a JSON array with objects to individual JSON objects separated by newlines.
- Can I convert nested JSON arrays to JSONL?
The converter handles top-level arrays by default. If you have nested arrays, they will remain as arrays within each JSON object in the JSONL output. For complex nested structures, you might need to pre-process your data to flatten it before conversion.
