LinkedIn Content Automation: AI Post Creation & Images with Sheet Approval Workflow

Who’s it for

This workflow is designed for marketers, content creators, agency owners, and solopreneurs who want to automate LinkedIn content creation using AI. It helps turn Google Sheets entries into complete LinkedIn posts, including text, image prompts, and AI-generated images.

What it does / How it works

The workflow monitors a Google Sheet for new campaign entries. When a row is added, it automatically collects details about the campaign, searches LinkedIn via Tavily to identify relevant trends, and turns the information into an AI-generated LinkedIn post using a local Ollama model or an LLM of your choice.
A second approval step lets you refine the text directly inside the sheet. Once approved, the workflow generates an image prompt, creates a ready-to-post visual with OpenAI Images, and finally publishes the post to LinkedIn.

How to set up

• Add your own Google Sheets Trigger credentials.
• Add Tavily, Ollama/OpenAI, and LinkedIn OAuth credentials.
• Replace the sample Sheet URL with your own.
• Set your LinkedIn account/person ID in the posting node.
