Merge Multiple Binary Objects into Single Item

This n8n workflow efficiently merges binary data from multiple input items into a single output item. Starting with a manual trigger, it uses a Code node to generate sample URLs for demonstration. An HTTP Request node then downloads files as binary data, producing multiple items each with a 'data' binary. The key 'Merge items' Code node iterates over inputs, collects binaries renaming them as 'data_0', 'data_1', etc., and outputs one item with a 'binary_keys' JSON field listing them.

Benefits include simplifying file handling in n8n—ideal when you need to bundle downloads or process files together without splitting logic. It saves time for developers automating multi-file tasks, avoiding manual binary management or external tools.

Use cases: Create ZIP archives from web downloads (pair with ZIP node), batch process images/emails attachments, consolidate API file responses, or prepare data for upload services requiring single-item binaries. Versatile for IT/dev tools, enhancing productivity in file-heavy automations.
