Cross-post social content from Google Sheets to 5 platforms with OpenAI images

This n8n template shows how to fully automate your social media workflow from Google Sheets to X, Threads, LinkedIn, Facebook, and Instagram — with AI-generated visuals.

Instead of manually writing, designing, and posting content, this workflow turns a single Google Sheet row into multi-platform posts plus a custom AI image that matches your message.

You write once. n8n posts everywhere.

How it works

• A scheduled trigger checks your Google Sheet for content marked “Ready To Post.”
• The post text is pulled from Sheets and sent to all text-only platforms (X and Threads).
• At the same time, an AI agent analyzes your post and generates a high-quality image prompt.
• GPT-Image creates a custom visual based on that prompt.
• The image is uploaded to ImgBB to create a shareable URL.
• That image + your caption are automatically posted to LinkedIn, Facebook, and Instagram.
• Finally, your Google Sheet is updated so you never repost the same content twice.

How to use

1. Add your posts to Google Sheets in the Content column.
2. Set Status = Ready To Post when you want it published.
3. Make sure all platform credentials are connected in n8n.
4. Turn the workflow on and let it run automatically.
