What This Workflow Does

This automation eliminates the tedious task of manually entering receipt data by automatically processing receipt images uploaded to Google Drive. When you drop a new receipt into a monitored folder, the workflow extracts vendor name, date, itemized purchases, and total amount using AI, logs everything to a Google Sheet, and sends you an email confirmation with a formatted summary.

Key Benefits

Save time:** No more manual data entry from receipts
Reduce errors:** AI-powered extraction ensures accuracy
Stay organized:** All expense data automatically tracked in one spreadsheet
Get notified:** Instant email confirmation when receipts are processed

Common Use Cases

Personal expense tracking and budgeting
Small business accounting and bookkeeping
Reimbursement documentation
Tax preparation record-keeping

Setup Requirements

Accounts needed:
Google Drive account (for receipt storage)
OpenAI account (for AI-powered data extraction)
Google Sheets account (for data logging)
Gmail account (for notifications)

Configuration steps:

Google Drive: Connect your account and select the folder where you'll upload receipts
Google Sheets: Make a copy of the template spreadsheet (link in workflow notes) to your own account and update the Sheet ID in the workflow
Email recipient: Change the notification email address to your own
AI model: The workflow uses GPT-4-mini by default, but you can select a different OpenAI model based on your accuracy and cost preferences

The AI Agent is configured to extract data in a strict JSON format with fields for vendor, date (converted to DD/MM/YYYY), itemized purchases, and total amount.
