Flatten

What It Does

Flattens an array of arrays into a single level array, combining all nested elements into one unified list.

Inputs

Name	Description	Type	Required
array	The nested list to flatten	List	Yes

Outputs

Name	Description	Type
array	The resulting flattened list	List

Array flatten Example

How to Use It

1. Drag the Array flatten node into your graph.

2. Connect a nested list (like [[1, 2], [3, 4]]) to the "array" input.

3. The node will output a single flattened list (like [1, 2, 3, 4]).

Tips

• This node only flattens one level deep, not recursively through all nested arrays.

• Make sure your input is actually an array of arrays, or the node will throw an error.
