Description:
This advanced n8n automation template checks the validity and production-readiness of multiple JSON workflow files using AI-powered analysis.
It scans a designated Google Drive folder for uploaded JSON files, downloads them one by one, parses their structure, and sends each JSON to GPT-4 via LangChain Agent for intelligent validation. Results are automatically logged into a Google Sheet with structured feedback.
Ideal for QA analysts, workflow engineers, or product teams maintaining large libraries of automation blueprints—this template removes manual review from your JSON pipeline.
What This Template Does (Step-by-Step)
🟢 Manual Trigger: Starts the flow when user clicks "Execute Workflow".
📁 Google Drive File Search: Connects to a specified folder (e.g., Edtech) and fetches a list of all JSON files.
🔁 Batch Processor (SplitInBatches): Loops through each file one-by-one to prevent overload or parallel conflicts.
📥 File Downloader: Downloads each file using its unique File ID from Google Drive.
📤 JSON Extractor: Converts each downloaded file from binary to structured JSON.
🤖 LangChain AI Agent + Azure GPT-4
🟢 Sends each JSON structure to a GPT-4-powered 🟢 LangChain Agent.
🟢 AI validates and analyzes:
- JSON structure integrity
- Presence of required nodes/connections
- Proper use of credentials
- Industry-readiness
🟢 Observations on modularity, error handling, or fragility
📊 Google Sheets Logger: Writes AI-generated insights back into a Google Sheet (e.g., tab: final) for team visibility and tracking.
Required Integrations
- Google Drive API (OAuth2)
- Google Sheets API (OAuth2)
- Azure OpenAI or OpenAI GPT-4 API Key
- LangChain AI Agent & Memory Modules
