JSON Lines
https://jsonlines.org/
JSON Lines text format, also called newline-delimited JSON.
The JSON Lines format has three requirements:
UTF-8 Encoding
Each Line is a Valid JSON Value
Line Separator is '\n'
Suggested Conventions
JSON Lines files may be saved with the file extension .jsonl.
Text editing programs call the first line of a text file "line 1". The first value in a JSON Lines file should also be called "value 1".
