When working with large datasets or streaming applications, you often need to convert JSON to JSONL format. JSONL (JSON Lines) is a convenient format where each line is a valid JSON object, making it perfect for processing large datasets line by line. Whether you're a data scientist, developer, or someone dealing with JSON data, converting to JSONL can significantly improve your data processing workflow.

What is JSONL and Why Convert JSON to JSONL?

JSONL (JSON Lines) format offers several advantages over traditional JSON:

• Each line is a complete, valid JSON object, making it perfect for streaming and processing data line by line.
• Easier to process large datasets as you don't need to load the entire file into memory.
• Ideal for log files and data pipelines where you want to append new records.
• Better compatibility with big data tools and frameworks that process data line by line.

Converting JSON to JSONL in Different Ways

Here are various methods to convert JSON to JSONL format using different tools and programming languages You can also consider going through the official JSON Docsfor better understanding::

Convert JSON to JSONL Using Python

import json

# Read the JSON file
with open('input.json', 'r') as f:
    data = json.load(f)

# Write to JSONL format
with open('output.jsonl', 'w') as f:
    # Handle both array of objects and single object
    if isinstance(data, list):
        for item in data:
            json.dump(item, f)
            f.write('\n')
    else:
        json.dump(data, f)
        f.write('\n')

This Python script handles both arrays of objects and single objects, converting them to JSONL format by writing each object on a new line.

Using jq to Convert JSON to JSONL

# For arrays of objects
jq -c '.[]' input.json > output.jsonl

# For objects that need to be converted to array first
jq -c '. | [.] | .[]' input.json > output.jsonl

The jq command-line tool provides a powerful way to convert JSON to JSONL. The -c flag produces compact output, putting each JSON object on a single line.
