Turning Complex File Submissions into a Seamless Workflow with n8n

A client reached out with a challenge: they were receiving multiple form submissions with files, and managing them manually was becoming overwhelming. Each file had to be processed, cleaned, sent through external APIs, and converted back into a usable format — all before combining the results.

I broke the problem into steps and built an automation workflow in n8n. Using a mix of extraction nodes, field edits, HTTP requests, custom code, and file conversion, I designed a system where every file was handled automatically and merged into one streamlined output.

The tools were straightforward yet effective — n8n as the automation backbone, code nodes for logic, and integration nodes for API communication. This made the process fully automated while staying flexible to the client’s needs.

The outcome was a smooth workflow that saved hours of manual work. Instead of juggling repetitive tasks, the client now has a reliable system running in the background. They felt a real sense of relief knowing their operations were finally under control.
