Description
Let a user load multiple files with a Form node, and process the binary data. A very important workflow for many tools.
This is a learning example of several core concepts that are hard to grasp in n8n:
$binary data
Loop and $runIndex
Split Out
The Save File deomonstrates how to access the binary data correctly, but could be swapped to POST the files to an AI, for example.
This workflow was created by Wyeth and shared publicly on the n8n community template library. n8nFind indexes it for discovery — the workflow remains the property of its original creator.
