Automate Invoice Data Extraction with Google Gemini & Sheets

Streamline your invoice processing with the power of automation! Our cutting-edge n8n workflow seamlessly integrates Google Gemini and Google Sheets to extract invoice data, ensuring precision and efficiency from document reception to confirmation alerts.

What this workflow does

• Receive & Process: The workflow begins by receiving an invoice file through an n8n chat trigger.
• Data Extraction: Harnessing the capabilities of Google Gemini, it extracts critical invoice information including vendor details, invoice number, date, total amount, and itemized line entries into a structured JSON format.
• Validation & Verification: The extracted JSON is checked against an existing Google Sheets log for missing fields and to prevent invoice duplication.
• Data Integration: Once validated, each line item is appended as a new row in your specified Google Sheets, complete with an HTML invoice breakdown for summary.
• Communication: Successfully processed invoices trigger a Gmail alert with a detailed HTML summary, while validation failures send an alert for quick acknowledgment.
