String Coordinate to BBoxes - Parse bbox strings to list

Node Purpose: String Coordinate to BBoxes parses a multiline string of bbox coordinates into a nested list structure suitable for downstream consumers.

Inputs

Name	Port	Type	Default	Range	Description
coordinates_string	-	STRING	``	multiline	Lines of bbox coordinates; separators can be spaces or commas; brackets []() are ignored. Each line should contain at least four numbers x1 y1 x2 y2.

Outputs

Name	Type	Description
bboxes	BBOXES	Nested list of bboxes in the form [ [ [x1,y1,x2,y2], ... ] ]. Returns [[]] when none are parsed.

Features

• Robust parsing: strips brackets and tolerates commas/spaces; converts floats to ints; ignores invalid tokens.
• Structure compatibility: produces a nested list suitable for consumers expecting grouped bboxes.

Typical Usage

• Provide one bbox per line (e.g., 12,34,200,180). The output groups all lines into a single inner list.

Notes & Tips

• When no valid boxes are found, the output is [[]].
