Description
This workflows helps with processing binary data.
You'll often have binary objects with keys such as attachment_0, attachment_1, attachment_2, etc. attached to your items, for example when reading an incoming email.

This workflow solves this problem by providing a Function node that takes all incoming items and all their binary data and then returning a single item for each file with a data key containing your binary file.
