NDJSONJSON

NDJSONJSON, also known as newline-delimited JSON, is a data format used for transmitting structured data. It consists of a sequence of JSON objects, where each object is on its own line, terminated by a newline character. This contrasts with a single JSON array that might contain multiple objects, as in a standard JSON file. The primary advantage of NDJSONJSON is its streamability and ease of parsing. Because each JSON object is self-contained and delimited by a newline, it can be processed line by line without needing to load the entire dataset into memory. This makes it particularly suitable for handling large datasets or real-time data streams where memory constraints or latency are concerns. When writing data in NDJSONJSON format, each distinct JSON object is placed on a separate line. For example, a file might contain: {"name": "Alice", "age": 30}\n{"name": "Bob", "age": 25}\n{"name": "Charlie", "age": 35}\n. When reading NDJSONJSON, a parser can simply read each line, parse it as a standard JSON object, and then proceed to the next line. This simple structure facilitates efficient data processing and transfer in various applications, including logging, data pipelines, and APIs.
