jsonlines Python Library

jsonlines is an active Python library (version 4.0.0) that provides helpers for working with the JSON Lines (also known as NDJSON) text file format. It simplifies reading and writing streams of newline-delimited JSON objects, offering features like transparent handling of string and byte streams, support for optional faster JSON parsers (like `orjson` and `ujson`), built-in data validation, and robust error handling. Its design prevents common pitfalls and ensures standard-compliant line breaking.
