Best Practice for Waiting on Two Google Sheets Before Continuing a Loop

[Kolinos]

Hi everyone,

I’m new to n8n and wanted to check if my approach makes sense. This is a simplified version of my workflow.

1. I loop over a set of items.
2. Each item is written to two Google Sheets (Sheet 1 and Sheet 2).
3. I need both Sheets to finish writing before the loop continues to the next item.

Here’s how I’ve set it up:

Items are processed in a loop.
Each item is sent to Sheet 1 and Sheet 2.
I use a “Merge” node after both Sheets to ensure both finish before proceeding.

Is this the correct way to handle this, or is there a better practice I should follow?

Thanks in advance!

Tip for sharing information

Pasting your n8n workflow

---

Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

That implies to any JSON output you would like to share with us.

Make sure that you have removed any sensitive information from your workflow and include dummy or pinned data with it!

Using Merge to ensure the two branches completed before proceeding is a legitimate apprach. Though it looks like both GSheet nodes do the same job (just different sheets). If that is the case, you might want to set a different Merge mode instead of “Append”. For example, you could pick “Choose Branch” mode. Othewise the “done” output of the Loop node likely to contain “duplicated” data (number of items) in case it matters for your use case.
