Build Batch Data
Zip per-row records with a generated images array into the data array a Compositor batch consumes.
Build Batch Data
Node type: utility:build_data
Category: Data
Description
Zips per-row text (an LLM JSON array like [{headline, stat}, ...]) with a generated images array into the data array a Compositor batch (the data port) consumes. Rows and images are paired by index, and each image URL is assigned to the configured key (default bg). This is the connector that bridges "generate at runtime" to "one reusable-layout Compositor renders N branded images".
Either input can be omitted: records alone produce rows without an image key; images alone produce rows containing only the image key.
Canvas ports
These appear as port handles on the left side of the node.

The result also exposes the same array as array and as a JSON string on text, plus a count of rows.
Notes
- Fails if the zip produces zero rows (nothing wired, or both inputs empty).
