✅ Use Case

Automatically generate AI images from prompts listed in a Google Sheet, upload the images to Google Drive, and log the result back into the sheet.

Uses the image-to-image-gpt API for fast, customizable generation.

💡 Problem It Solves

Manual image generation workflows are inefficient and error-prone. Creative and content teams often have to:

This automation removes all that friction—turning one spreadsheet into a complete image creation pipeline.

Node	Description
1. Manual Trigger	Starts the workflow when executed manually
2. Google Sheets2	Reads all rows from the input Google Sheet
3. Loop Over Items	Processes one row (prompt) at a time
4. If2	Filters only rows where `Prompt` is not empty and `drive path` is empty
5. HTTP Request1	Calls the `image-to-image-gpt` API with the prompt
6. If1 (Error Handling)	If an error exists in the API response, route to logging
7. Google Sheets4 (Error Log)	Appends error details to a log sheet for review
8. Code1	Decodes the base64 image returned by the API
9. Google Drive1	Uploads the image to a selected Google Drive folder
10. Google Sheets1 (Write Back)	Updates the original row with the image drive path and timestamp
11. Wait	Delays the next prompt to prevent hitting API rate limits

Your Google Sheet should include the following columns:

Column	Purpose
`Prompt`	The AI prompt to send to the API
`Image url`	(Optional) Initial image URL
`drive path`	Updated with Drive link by flow
`Generated Date`	Auto-filled by the workflow
`Base64`	Stores raw or error data

You can add a Cron node if you want this to run on a schedule
Use a separate tab/sheet for logging failed prompts
Extend the flow by adding:
- Email notifications
- Slack alerts
- File name templating
