Mapping: JSONL Slicer

Keep only a contiguous range of lines from a JSONL file. Both bounds are optional — leave them empty to extend the range to the beginning or the end of the file.

Input

JSONL file—REQUIRED

Source JSONL file to slice.

Parameters

Start line

The first line you want to keep. Lines are numbered from 1. Leave empty to start from the very beginning of the file.

End line

The last line you want to keep — this line is included. Leave empty to read all the way to the end of the file.

Output

JSONL file

A new JSONL file containing only the lines within the configured range.
