Overview

📊 Description

Automate the optimization of your n8n workflows using AI-powered analysis and restructuring 🤖. This workflow receives any existing n8n JSON via webhook, analyzes it using Azure OpenAI, and returns a fully optimized, import-ready workflow file. It improves execution speed, reduces redundant nodes, enhances API efficiency, and ensures structural cleanliness — all while preserving the original logic. Perfect for automation builders who want cleaner, faster, and production-ready workflows instantly. 🚀

What This Template Does

📥 Receives an n8n workflow JSON via a secure POST webhook. 🔍 Extracts and validates the workflow body to ensure proper structure. 🤖 Sends the workflow to Azure OpenAI for performance and structural optimization. 🧹 Strips markdown, parses, and validates the AI-returned JSON. 📄 Converts the optimized workflow into a downloadable .json file. 📤 Returns the optimized workflow file directly to the caller.
