Split Binary Data into Individual Files

This workflow addresses a common challenge in n8n: handling binary data objects that aren't in a simple array format, such as multiple attachments from incoming emails named 'attachment_0', 'attachment_1', etc. The core Function node iterates through all incoming items and their binary properties, creating a new item for each binary file. Each output item includes a JSON object with the filename and a 'data' binary key containing the file data. Benefits include simplifying downstream processing
