N8n2LangGraph Converter

Purpose

CLI tool that converts n8n workflow JSON exports into standalone LangGraph + LangChain Python scripts using OpenAI Responses API. Normalizes n8n graph → translates nodes via pluggable translators → generates StateGraph code.

Architecture

• Single script: n8n_to_langgraph.py
• Pluggable node translators for Set, IF, HTTP Request, Code, OpenAI/LLM nodes
• Optional reflection loop and agentic re-prompting
• LLM-assist for unsupported nodes
• Optional black formatting for generated code

Key Features

• Converts n8n JSON workflow exports to LangGraph StateGraph Python code
• Pluggable translator architecture for different node types
• Optional reflection loops for workflow refinement
• Agentic re-prompting for complex translations
• LLM-assisted fallback for unsupported node types
• Optional code formatting with black

Dependencies

• openai
• langgraph
• langchain-core
• requests (runtime)
• black (optional)

Key Claims

• Converts n8n workflow JSON into standalone LangGraph Python scripts, with optional reflection loops and LLM-assisted translation for unsupported nodes.

Open Questions

• Could N8n2LangGraph be used to convert workflows into DeepAgent Azure CLI custom tools?
