Convert n8n automation workflow JSON files into clean, executable Python scripts — instantly.

You have an n8n workflow like this:

[Schedule] → [HTTP Request] → [Send Slack Message] 

Run one command:

python converter.py my_workflow.json

And get a ready-to-run Python file:

import schedule, time, requests from slack_sdk import WebClient def run_every_day_at_9am(): response = requests.get("https://api.example.com/data") data = response.json() client = WebClient(token=os.getenv('SLACK_TOKEN')) client.chat_postMessage(channel="#general", text=str(data)) schedule.every().hour.do(run_every_day_at_9am) while True: schedule.run_pending() time.sleep(60)

git clone https://github.com/yourusername/n8n-workflow-to-python cd n8n-workflow-to-python pip install -r requirements.txt

No external libraries are needed for the converter itself — only for the generated scripts (e.g. requests, slack-sdk, etc.).

Basic:

python converter.py workflow.json

Custom output filename:

python converter.py workflow.json -o my_automation.py

Verbose mode (shows all nodes and connections before converting):

python converter.py workflow.json --verbose

Help:

python converter.py --help

1. Try the included example:

python converter.py examples/slack_alert.json --verbose

2. This produces slack_daily_alert.py — open it, fill in your credentials, run it.

The converter has 6 steps:

1. Load — reads the JSON file with json.load()
2. Extract nodes — parses each node's name, type, and parameters
3. Extract connections — builds the execution flow from node to node
4. Map types — looks up each node type in a templates dictionary
5. Generate code — calls the matching generator function per node
6. Write file — outputs a complete, formatted Python script

Each n8n node type has its own generator function (e.g. _gen_http_request, _gen_slack_node). Adding support for a new node type means adding one function.

Generated scripts use os.getenv() for credentials. Create a .env file:

SLACK_TOKEN=xoxb-your-token OPENAI_API_KEY=sk-your-key ANTHROPIC_API_KEY=sk-ant-your-key GMAIL_USER=you@gmail.com GMAIL_PASSWORD=your-app-password AIRTABLE_TOKEN=pat-your-token DATABASE_URL=postgresql://user:pass@localhost/db NOTION_TOKEN=secret_your-token

Install python-dotenv and the script loads it automatically:

pip install python-dotenv

Want to add support for more node types? It's easy:

1. Add a new function _gen_yournode(node) that returns a list of Python code lines
2. Add it to the NODE_TEMPLATES dict with the node's type string

Example:

def _gen_telegram_node(node): return [ "# Telegram — send message", "import requests", f"requests.post(f'https://api.telegram.org/bot{{os.getenv(\"TELEGRAM_TOKEN\")}}/sendMessage', ...)", ] NODE_TEMPLATES["n8n-nodes-base.telegram"] = _gen_telegram_node
