NDJSON	File extension: NDJSON
	File type:	newline-delimited JSON data file

What is an NDJSON file

NDJSON files mostly belong to Text Editor. NDJSON files are files where each line is a complete JSON object arranged one after another. This newline-delimited JSON format lets you work with each record separately, which is ideal when processing streams of data or working with large logs.
Details include:

Data streaming: Each line is an individual JSON record, allowing systems to read and process data incrementally.

Incremental updates: New records can be appended easily without needing to parse the entire file.

Internal file use: Formats like these are used in workflows, for example within the Apple App Privacy Report, to efficiently manage data.

FilExt.com note: You can open NDJSON files in any advanced text editor or use command-line processors like jq to filter and view the data.

How to open an NDJSON file

You need a suitable software like Text Editor to open an NDJSON 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 NDJSON file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NDJSON file directly in the browser:. Just drag the file onto this browser window and drop it.

A newline-delimited JSON, or NDJSON, file is a plain text file composed of multiple JSON objects, each of which is delimited by a newline character. Each line in the file is a valid JSON object, allowing for easy parsing and processing of large datasets. NDJSON offers a simpler and more efficient alternative to traditional JSON arrays for storing and transmitting structured data, especially in big data applications where dealing with massive JSON arrays can be cumbersome. It is particularly well-suited for streaming data and log files, as each line can be processed independently without loading the entire file into memory. The newline character ensures that each JSON object is self-contained, enabling efficient parsing and appending of new data. While traditional JSON files require parsing the entire file at once, NDJSON's line-by-line structure allows for incremental processing, making it ideal for handling large datasets and real-time data streams. This file format is classified as Data Interchange Format.
