JSONL is a text-based format using the .jsonl file extension that is basically the same as JSON format but implemented using newline characters to separate JSON values.  It is also known as JSON Lines.   Manifold can import and link JSONL files.  Manifold can also export tables to JSONL files.  JSONL is used in GeoJSONL format.



There are three key differences between JSON format and JSONL format:


Exporting to JSONL

Manifold can export tables to JSONL.   Binary fields are ignored and are not exported.


Please read the JSON topic for important information about JSON format and Manifold that, with one key difference in addition to the above, applies to JSONL format as well.   The key difference between JSON and JSONL when importing files is that an entire JSON file can be no larger than 2 GB, while there is no limit on the size of a JSONL file so long as any single line within the file is no larger than 2 GB.
