Description
🧰 Instagram Carousel Scheduler
A tool to automatically publish Instagram carousels using a Post Description, Instructions, and the number of images you want to post — all directly from a Google Sheet.
At the end of each post, the next row is marked as Pending, allowing fully automated posting, so you can prepare months of content in advance.
✅ Requirements
-
📱 Instagram Business Account Required to publish content via the Meta Graph API. Make sure your IG account is connected to a Facebook Page.
-
🔐 Facebook Developers Token Required to use the Graph API and publish on Instagram. 👉 It’s highly recommended to create a System User so your token never expires.
-
☁️ Cloudinary Upload Preset Used to upload generated images and retrieve public URLs. 👉 Use an unsigned upload preset (no API key required).
-
🧠 OpenAI API Key Used for:
- Generating a caption from the post description.

📊 Google Sheets App with OAuth credentials To fetch your content and instructions from the spreadsheet.
