Ever wondered how you can effortlessly combine data from multiple streams to supercharge your workflows? Well, buckle up because I’m about to show you how the n8n Merge node can transform the way you handle data. It’s like having a Swiss Army knife for your data integration needs. Let me tell you, once you get the hang of this, you’ll wonder how you ever managed without it.
So, what exactly is the n8n Merge node? It’s a powerhouse tool within the n8n platform that lets you combine data from multiple streams once all the data is available. Whether you’re scraping websites, building a Telegram AI chatbot, or just joining different datasets, this node is your go-to solution. And guess what? It’s been overhauled and upgraded to make it even more versatile and powerful.
What’s New with the Merge Node?
Let’s dive into the juicy updates. Back in n8n version 0.194.0, the Merge node got a major facelift. It was like giving a classic car a modern engine. Then, in version 1.49.0, they added the ability to handle more than two inputs and introduced the SQL Query mode. Talk about leveling up your data merging game!
How Does the Merge Node Work?
The Merge node offers multiple modes for combining data: Append, Combine, and SQL Query. Let’s break them down:
- Append Mode: This mode keeps data from all inputs and outputs it sequentially. Simple, yet effective.
- Combine Mode: Here’s where the magic happens. You can merge data from two inputs with options like Matching Fields, Position, and All Possible Combinations. It’s like having a custom-tailored suit for your data.
- SQL Query Mode: Want to get fancy? Use custom SQL queries to merge data from inputs treated as tables. It’s like speaking the language of data directly.
Within Combine mode, you’ve got even more options. You can handle clashes, use fuzzy comparisons, disable dot notation, and manage multiple matches and unpaired items. It’s like having a Swiss Army knife with a blade for every possible scenario.
Exploring Combine Mode Options
Let’s zoom in on Combine mode because it’s where the real fun begins:
- Matching Fields: Compare items by field values with options for output types like Keep Matches, Keep Non-Matches, Keep Everything, Enrich Input 1, and Enrich Input 2. It’s like having a magnifying glass for your data.
- Position Mode: Merge items based on their order in the input streams. It’s like arranging your data in a parade.
- All Possible Combinations: Output all possible item combinations. It’s like creating a data buffet.
And don’t forget about Clash Handling. When fields in multiple items have the same name, you need a way to manage those conflicts. The Merge node has you covered.
SQL Query Mode and Choose Branch Mode
Now, let’s talk about the SQL Query mode. This is where you can get really creative. By treating your inputs as tables, you can write custom SQL queries to merge data exactly how you want it. It’s like having a chef’s kitchen for your data.
And if you just need to select which input’s data to output without modification, there’s the Choose Branch mode. It’s like having a traffic cop directing your data flow.
Handling Uneven Numbers of Items
Ever dealt with uneven numbers of items? No worries. The Merge node prioritizes items from Input 1. It’s like having a VIP list for your data.
Legacy Considerations
In older versions of n8n (0.236.0 and below), the Merge node could affect the execution behavior of If nodes. It’s something to keep in mind if you’re working with legacy systems. But don’t let that stop you from using this powerful tool.
Practical Examples and Templates
