import jsonlines

with jsonlines.open('example.jsonl', 'r') as jsonl_f:
     lst = [obj for obj in jsonl_f]

The jsonl_f is the reader and can be used directly. It contains the lines in the json file.

JSON Lines

This page describes the JSON Lines text format, also called newline-delimited JSON. JSON Lines is a convenient format for storing structured data that may be processed one record at a time. It works well with unix-style text processing tools and shell pipelines.

Reader for the jsonlines format. · The first argument must be an iterable that yields JSON encoded · strings. Usually this will be a readable file-like object, such as · an open file or an ``io.TextIO`` instance, but it can also be · something else as long as it yields strings when iterated over.

jsonlines.Reader accepts iterable as an arg ("The first argument must be an iterable that yields JSON encoded strings" not json-encoded single string as in your example), but, after .decode("utf-8"), log would be a string, which happen to support iterable interface. So when reader calls under the hood next(log) it will get first item of a log string, i.e. character { and will try to process it as an json-line which would be obviously invalid. Try log = log.split() before passing log to the Reader.

1 week ago - JSON Lines (a.k.a. newline-delimited JSON) is a simple format for storing sequences of JSON values in which each value is serialized on a single line and terminated by a newline sequence. The `serde-jsonlines` crate provides functionality for reading & writing these documents (whether all at once or line by line) using `serde`’s serialization & deserialization features.
