Accumulation to List¶
Converts an Accumulation object into a plain list. This node extracts the internal accumulated items (kept under the 'accum' container) and returns them as a single list output. It preserves the order in which items were accumulated.
Usage¶
Use this node after one or more accumulation steps (e.g., after using Accumulate or other Accumulation manipulation nodes) when you need a standard list to feed into downstream nodes that expect a list rather than an Accumulation. Typical workflow: build up items with Accumulate → optionally inspect or modify → convert to list here → process the list elsewhere.
Inputs¶
| Field | Required | Type | Description | Example |
|---|---|---|---|---|
| accumulation | True | ACCUMULATION | The Accumulation object holding items in its internal 'accum' list. Usually produced by Accumulate or List to Accumulation. | {'accum': ['item_a', 'item_b', 'item_c']} |
Outputs¶
| Field | Type | Description | Example |
|---|---|---|---|
| accumulated_list | * | A plain list of the accumulated items extracted from the provided Accumulation. | ['item_a', 'item_b', 'item_c'] |
Important Notes¶
- Output is a single list: The output socket emits one list containing all items; it is not a list of multiple outputs.
- Type-agnostic items: Items inside the list can be of any type; this node does not enforce a specific element type.
- Graceful fallback: If the input is missing or not a valid Accumulation, the node returns an empty list.
- Order preserved: Items appear in the list in the same order they were accumulated.

Troubleshooting¶
- Empty list output: Ensure the input comes from a node that outputs ACCUMULATION and that it contains items. If the Accumulation is uninitialized or malformed, this node returns an empty list.
- Type mismatch: If downstream nodes reject the output, check their expected element types. While this node allows any element type, downstream nodes may require specific types.
- Unexpected single item wrapping: If previous steps did not produce a proper Accumulation, convert with List to Accumulation first to ensure correct structure.
