Joining different datasets

n8n template #1747

Summary

Task: Merge two datasets into one based on matching rules Why: A powerful capability of n8n is to easily branch out the workflow in order to process different datasets. Even more powerful is the ability to join them back together with SQL-like joining logic. Main use cases: Appending data sets Keep only new items Keep only existing items

How to set it up

Open template #1747 on n8n.io and click Use for free, or copy the template JSON and paste it onto an empty canvas in n8n.
No app accounts to connect: every node is built into n8n.
Click Execute workflow and step through each node's output to confirm the data looks right.
Toggle the workflow to Active so its trigger runs on its own.
