Generate and Split Sample Data Records Using JavaScript and Python

A minimal, plug-and-play workflow that generates **sample data** using n8n's **Code** node (both JavaScript and Python versions included) and then **fans out** those records into individual items with **Split Out**. Perfect for testing downstream nodes, mapping, pagination, or prototyping list-based logic without connecting to real data sources. --- ## What this template does - **Generates 20 sample records** with fields: `index`, `num`, and `test` - Writes the array to `item.json` - Uses **Split Out** to convert the array into **one item per record** - Includes **both JavaScript and Python** implementations side-by-side --- ## Who's it for - Builders who need **mock data** to test mappings and loops - Educators/demo makers who want a simple **fan-out pattern** - Anyone who wants a **clean scaffold** for list processing in n8n --- ## How it works / What it does - **Generate Data Javascript**: Produces `barr = [{ index, num, test }, ...]` for 20 rows - **Generate Data Python**: Same output, written in Python - **Split Out Javascript / Python**: Takes `barr` and emits **one item per element** > Use either branch (JS or Python) depending on your preference. --- ## How to set up No external setup required. Import the workflow and **Execute**. Select either the **JavaScript** or **Python** branch to see fan-out items. --- ## Requirements - n8n (Cloud or self-hosted) - No credentials or third-party services --- ## Customize the workflow - Change the number of rows: adjust the loop range (`0..N`) - Rename or add fields to each record (e.g., `name`, `price`, `tags`) - Replace the static array with generated or randomized data - Pipe the Split Out output into **Set**, **Function**, **HTTP**, or **Sheets** nodes for further testing --- ## Notes - Sticky notes are included for in-editor guidance. - Both implementations return the same structure so you can swap freely. --- ## Contact Need help customizing this (e.g., shaping fields, adding randomizers, or exporting to CSV/Sheets)? - 📧 **rbreen@ynteractive.com** - 📞 **Robert Breen** - https://www.linkedin.com/in/robert-breen-29429625/ - 🌐 **ynteractive.com** - https://ynteractive.com
