Automated Trip Expense Claim Form With OpenAI & Drive

Overview
This workflow streamlines business travel expense reporting. Instead of manually typing from receipts, it validates PDFs, stores them, extracts all fields with AI, and produces a report ready for finance review.

How it works

• Upload your receipts in PDF format.
• Each file is validated and stored in Diaflow Drive.
• GPT-5 extracts key data (employee, trip purpose, vendor, totals).
• Data rows are written into Google Sheets for record-keeping.
• A formatted HTML report is generated and sent via Gmail to the finance team.

When to use it
Perfect for organizations where employees submit multiple trip receipts. It ensures files are archived, expenses are logged consistently, and finance receives a ready-made summary without manual effort.
