Who this is for Every who's interested in seeing how merging items works in n8n What this workflow does This workflow generates two sets of sample data: one with names and corresponding languages, and another with greetings and corresponding languages using the Code node. It then merges these two datasets using the Merge node based on the common “language” field, combining all entries that share the same language.

This is an example of how you can make Merge by Key work. The “Data 1” and “Data 2” nodes simply provide mock data. You can replace them with your own data sources. Then the “Convert Data” nodes are important. They make sure that the different array items are actually different items in n8n. After that, you have then the merge with the merged data.
Write JSON to Disk (Binary)
The “Write Binary File” expects binary data. The JSON data is, however, JSON ;) There should really be a node that allows moving data around between both of them. For now, it can be done with a Function-Node. At least till a proper one is in place. The first node is example data, wich you can customize or replace. The second node named “Make Binary” is the important one with the custom code which makes the data binary and writes it to the correct location.
Webhook returning XML
