JSONL to JSON Converter - Convert JSON Lines to JSON Array
Convert JSONL (JSON Lines) to JSON arrays online. Transform newline-delimited JSON into standard JSON array format for data analysis.
How to Convert JSONL to JSON - Step by Step Guide
Input Your JSONL Data
Start by adding your JSONL (JSON Lines) data that needs to be converted to a JSON array. Each line should contain a valid JSON object. Also try JSON to JSONL, JSON validator, or formatter.
Example: Try This JSONL Data
Copy and paste this JSONL example to see conversion:
{"id":1,"name":"Alice","status":"active"} {"id":2,"name":"Bob","status":"inactive"} {"id":3,"name":"Charlie","status":"active"}
Configure JSON Output Options
Customize how your JSONL data is converted to JSON array format! Choose indentation and formatting options.
Get JSON Array Output
See your JSONL data transformed into a standard JSON array!
JSON Array Output Result
Your JSONL lines become this JSON array:
[ { "id": 1, "name": "Alice", "status": "active" }, { "id": 2, "name": "Bob", "status": "inactive" }, { "id": 3, "name": "Charlie", "status": "active" } ]
Perfect for data analysis and JSON APIs
Download or Copy JSON Array
Perfect! Now you can use your JSON array in APIs, applications, and data analysis tools.
What is JSONL to JSON Conversion?
JSONL to JSON conversion transforms newline-delimited JSON (where each line is a separate JSON object) into a standard JSON array format. This makes JSONL data from log files, streaming sources, or data pipelines compatible with standard JSON processing tools and APIs.
The conversion parses each line independently and combines them into a single JSON array, making it easier to work with the data in applications that expect standard JSON arrays. This is particularly useful for analyzing log files, processing batch data, or preparing data for visualization and reporting tools.
Frequently Asked Questions
Why convert JSONL to JSON array?
Converting JSONL to JSON arrays makes the data compatible with standard JSON tools, APIs, and visualization libraries. While JSONL is great for streaming and logging, JSON arrays are better for batch processing, API responses, and data analysis. Learn more in our JSON vs JSONL comparison.
What happens if one line in the JSONL is invalid?
The converter validates each line independently and will report exactly which line contains invalid JSON. This helps you identify and fix errors quickly. The error message includes the line number and details about what went wrong.
Can I convert large JSONL files?
Yes! The converter handles large JSONL files efficiently. However, keep in mind that the resulting JSON array will be larger than the original JSONL due to array syntax. For very large files, consider processing them in chunks or using streaming approaches.
Does the converter preserve nested objects and arrays?
Absolutely! The converter preserves the complete structure of each JSON object, including nested objects, arrays, and all data types (strings, numbers, booleans, null). The structure remains identical, just wrapped in a JSON array.
Can I customize the indentation of the output?
Yes! You can choose between 2-space indentation, 4-space indentation, or compact format (no extra whitespace). Use pretty-printed format for readability during development and compact format for production or data transfer.
Is the JSONL to JSON converter free to use?
Yes, completely free with no limitations on file size, conversion frequency, or output features. No registration required, and you can convert unlimited JSONL data to JSON format at no cost.
