Slice List
Uncontrolled node
Overview
The Slice List node extracts a portion of a list based on start and end index values.
It behaves similarly to JavaScript's native .slice(start, end) function:
- The start index is inclusive.
- The end index is exclusive.
Use this node to extract segments, paginate data, or focus on a range of values from any list.
Inputs
| Input | Type | Description | Default |
|---|---|---|---|
| List | List | The list to slice | - |
| Start | Number | Index to start slicing from (inclusive) | 0 |
| End | Number | Index to stop slicing at (exclusive) | List length |
Outputs
| Output | Type | Description |
|---|---|---|
| Output | List | The sliced portion of the original list |
Panel Controls
No additional side-panel controls. Slicing behavior is controlled entirely by the Start and End inputs.
- If Start is missing, invalid, or not a number, it defaults to
0. - If End is missing, empty, or invalid, it defaults to the full length of the list.
- Both values are automatically rounded down using
Math.floor.
Example 1: Standard Slice
List:
["a", "b", "c", "d", "e"]
Start:
1
End:
4
Output:
["b", "c", "d"]
Tip
This node does not treat negative numbers as Python-style reverse indexing. A start of -2 will begin slicing from the end only if used directly, per JavaScript behavior.
