Merge disparate json data sources for AI analyis

[origin8]

I have 3 different data sources (json) I would like to send for reference with an AI agent node, and they appear as input for the AI tool, but I can only reference the first one with a json reference. I’ve checked the schema of the merged json, and all 3 sources are there, but I can only reference the first. They each have their own unique structures, but that doesn’t come up as a problem when merging. I don’t know how else to get all 3 sources into the node for analysis, but I can’t sadly reference each to reference in my prompt

Please share your workflowy

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Hey @origin8,

Please share your workflow JSON code here.
Just select your nodes, copy them, and paste inside a code block like this:

In the meantime, I’ll try to help based on your description:

N8N executes each node as many times as there are items in the input.
For example, if your JSON input has 3 items, the node will run 3 times—once for each item.

When using an expression like $json.name, you’ll only see the value of the first item in the editor.

However, during execution, the node processes each item separately, using the corresponding value for each run.

Hope that helps! If this answers your question, please remember to mark my reply as a solution.
