	File type:	data file

What is a JSONL file?

JSONL files mostly belong to jq. A JSONL file stores data in a newline-delimited JSON format. Each line is a valid JSON object, which can be processed one record at a time.
How it works:

Every line is an independent JSON object.

This enables streaming or batch processing of large datasets.

The line structure makes it easy to parse and analyze records separately.

Usage: These files are used for log storage, data exchange, and stream-processing tasks. Tools like jq can be used to filter and manipulate the data.
FilExt.com note: They are also suitable for use in data pipelines where incremental processing is required.

How to open a JSONL file

You need a suitable software like jq to open a JSONL file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your JSONL file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a JSONL file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert JSONL files:

jq
See the previous paragraphs to learn more about the main application. JSONL files are often referred to as jq data files because this type of file is primarily created or used by this software.
jq
JSON Lines (JSONL) files are plain text files consisting of multiple JSON objects, each on a separate line, making them easy to process line by line. They are particularly well-suited for storing and processing structured data, especially in situations where the data is too large to fit comfortably in memory. Their simple structure also makes them ideal for streaming data processing and use with command-line tools like jq. While each line must be valid JSON, the file as a whole is not a valid JSON document. This newline-delimited format allows for efficient processing of individual JSON objects without needing to parse the entire file at once. This file format is classified as Data Interchange Format.

How to solve problems with JSONL files

Associate the JSONL file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest JSONL file format. Search, therefore, e.g. on the manufacturer website after an available jq update.
To make sure that your JSONL file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
