Roadmap for building AI agents for Google workspace 🤔

Gemini API

Prior to prompting Gemini 2.5, I’d like your insights on the right approach to building agents for my workspace.
I’d like an agent that reads:

  • purchase orders I receive in PDF and records the data in my Sheets.
  • my expense receipts (uploaded by my phone) and records the data in a specific Sheets too.
  • among other things…
    What do you recommend for best integration with the Google ecosystem? Or does it not matter and I could just automate things with a solution like n8n?

Hi @Fred_Klass Apologies for late response
You can build powerful agents for Google Workspace using Vertex AI Agent Builder(or Google Workspace Flows) and the Gemini 2.5 API. For processing purchase orders and expense receipts from PDFs/images, Google Cloud Document AI is crucial for accurate data extraction. Google Apps Script will connect this extracted data directly to your Google Sheets for automated recording. Prioritize clear triggers, robust error handling, and leverage pre-trained Document AI processors for best results within the Google ecosystem.
Please let me know if you ahve any issue when building.
Thank you

Thanks!
What’s the difference btw the Custom extractor to “Extract structures and entities from documents” and the Expense parser - formerly receipt parser (Pretrained processor charges)?

Expense Parser is a pre-trained solution specifically for receipts, offering out-of-the-box accuracy for common fields with no training needed.
Custom Extractor requires you to define and train it on your specific document layouts to extract custom entities, ideal for unique documents like your purchase orders. For your receipts, the Expense Parser is best; for purchase orders, a Custom Extractor offers the necessary flexibility.
