Automate Facebook & Instagram Posts with AI & Google Sheets

Transform your social media management with this intelligent n8n workflow that combines AI-powered content creation with Google Sheets inventory tracking and human approval controls. Perfect for social media managers and marketing agencies who need scalable automation without sacrificing content quality.

What this workflow does

This complete social media auto-poster reads your product inventory directly from Google Sheets, intelligently identifies items that haven't been promoted recently, and leverages OpenAI to generate professional, engaging captions tailored for each platform. The workflow includes a built-in approval gate that pauses automation and sends you a web form for content review. Once you click "Approve," it automatically publishes to both Facebook and Instagram via the Facebook Graph API, then logs the successful post back to your Google Sheet for future tracking.

Key features

• Smart Google Sheets integration: Uses your spreadsheet as an intelligent inventory tracker to prevent over-promotion of the same products
• AI-powered copywriting: OpenAI automatically drafts platform-optimized, emoji-free captions based on your product data
• Human approval control: Built-in approval gate with n8n web form ensures quality control before publishing
• Dual-platform posting: Direct Facebook Graph API connection publishes to Facebook Pages and Instagram Business accounts simultaneously

Use cases
