⚡ 5,409 views · 📁 File Management
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.
