Today’s n8n Learning: Handling File Uploads and Binary Data

Today, I explored how file uploads and binary data work in n8n by building a simple hands-on workflow.

🔄 Workflow I Practiced

Form Submission → File Upload → Extract Data → Convert File → Edit Required Fields

💡 What I Learned

✅ Form Trigger – Created an n8n form where users can upload a file.

✅ Binary Data – Understood that when a file is uploaded through the form, n8n handles the uploaded file as binary data so it can be processed by other nodes.

✅ Extract from File – Learned how to extract structured data from an uploaded Excel/XLS file.

✅ Convert to File – Explored how data can be converted into a file format for further processing or storage.

✅ Edit Fields – Learned how to select and map only the required fields, such as Product ID and Category.

🎯 My Key Takeaway

The biggest learning for me today was understanding the difference between file/binary data and JSON data in n8n, and how we can move between them while building an automation workflow.

This is a small workflow, but it helped me understand an important concept that can be used in real-world automations—for example, uploading an inventory file, extracting product information, transforming the required fields, and then processing that data automatically.

One step at a time, building my n8n automation skills! 🚀
