Automating LinkedIn & Instagram Carousels with Make

[Msquare_Automation]

Carousels are one of the best content formats to educate and build trust on LinkedIn and Instagram.
But designing them every day in Canva, exporting, uploading, and posting manually… it takes a lot of time.

So I built a simple automation using Make that does everything for me.

I only add topics in Google Sheets.
The system creates the carousel images using AI and posts them automatically to both Instagram and LinkedIn.

Let me walk you through how this works in a very simple way.

1. Google Sheets – Where everything starts

I have a Google Sheet with just one column: Topic.

Example:

• Life of an AI Generalist
• Automation for Small Businesses
• CRM Tips for Beginners

Whenever I add a new row, Make detects it using Watch New Rows.
This becomes the trigger for the whole automation.

If I want one post per day, I just add one topic per day. That’s it.

2. AI – Creating the carousel structure

Next, the topic goes to an AI module (OpenAI / Gemini).

Here, I give clear instructions like:

• Create 5 carousel slides
• Each slide should have a title and short text
• Keep the style clean and readable
• Return everything in JSON format

The output looks like:

• Slide 1: Hook
• Slide 2–4: Main points
• Slide 5: CTA

This structured output makes it easy to automate image creation.

3. Image generation – One image per slide

Each slide from the AI output is sent to an image generation API (I used Freepik, but you can use any).

Make loops through:

• Slide 1 → Image 1
• Slide 2 → Image 2
• …
• Slide 5 → Image 5

All images are collected using an Array Aggregator.

Now we have a full carousel set.

4. Posting to Instagram

Instagram Business has a Create Carousel Post module.

I simply map:

• The array of image URLs
• The caption (topic or short hook text)

Make publishes the carousel automatically.

5. Posting to LinkedIn (as a document carousel)

LinkedIn needs a PDF for carousel posts.

So the flow is:

1. Create a Google Slides file from a template
   
   
2. Insert each generated image into one slide
   
   
3. Export the presentation as PDF
   
   
   
   4 Upload the PDF to LinkedIn
   
   
4. Create a Document Post using the uploaded file
   
   

All of this happens inside Make.

The same carousel now appears on LinkedIn as a swipeable document post.

Final Result

From just one row in Google Sheets:

• AI writes the slide content

• AI creates the visuals

• Make builds the carousel

• Make posts to Instagram
  

  
  
  
  

• Make posts to LinkedIn
  

  

Completely hands-free.
