Description

Intro:
The purpose of this workflow is to simply convert you planned Grocery delivery confirmation email to a Google Calendar event in your family calendar. While based on a Monoprix.fr email format, it is applicable/adaptable to almost anything else.

How it works:
It is triggered by reception of the confirmation email on your Gmail. The workflow then extracts relevant data using ChatGPT, formats it, and creates a Google Calendar event.

Steps to use it:
Import template in your n8n
Update credentials for Gmail, Google Calendar, and ChatGPT
Test workflow based on confirmation email received
Activate workflow
