Automate Calorie Logging from Food Images to Google Sheets via LINE and OpenAI

This workflow enables LINE users to send food images or text to a LINE bot, which then analyzes the images using OpenAI's Vision model to estimate calories and logs the results into Google Sheets.

The workflow integrates LINE Messaging API with n8n to process user inputs. Text messages receive direct responses from an AI agent, while image messages trigger a sequence of actions: downloading the image, analyzing it for food content, estimating calories using OpenAI's Vision model, and logging the results in Google Sheets. Users receive real-time feedback via LINE, confirming the logging of detected dishes and their calorie content.
