Automated Purchase Order Processing from Outlook XLSX
Automates purchase order intake by monitoring Outlook emails with XLSX attachments, converts Excel to markdown, uses OpenAI LLM (gpt-4o-mini) to extract structured PO details, validates entries, and sends automated email confirmations or rejections, saving time on data entry and error checking.
Apps in this workflow
How it works
- Microsoft Outlook Trigger1
- Text Classifier2
- If3
- Extract from File4
- Microsoft Outlook5
- Code6
- Information Extractor7
- Edit Fields8
- OpenAI Chat Model9
The building blocks this workflow uses, in the order data flows through them.
What you'll need
- An n8n instance (self-hosted or n8n Cloud).
- A Microsoft Outlook account, connected in n8n as a credential.
- An API key for OpenAI in n8n: the workflow calls the model each time it runs.
Gydmation shows step-by-step credential setup for each app, so your keys go straight into n8n and never to Gydmation.
