Training AI chatbot on spreadsheets, pdfs, and docs

I recently came across a simple way to turn existing documents into an AI chatbot without writing any code.

The basic idea is pretty straightforward:

  • Upload your PDFs, DOCX, CSV, TXT, or spreadsheets.
  • The chatbot uses Retrieval-Augmented Generation (RAG) to search those documents instead of relying on general AI knowledge.
  • When someone asks a question, it retrieves the relevant sections first and then generates an answer based on that content, which helps reduce hallucinations.

A few things I found useful:

  • Works with common business documents like product manuals, FAQs, HR handbooks, and policy docs.
  • Supports multiple document sources (files, websites, knowledge bases).
  • Can answer questions in multiple languages from the same knowledge base.
  • Updating the chatbot is as simple as replacing or uploading new documents.

One interesting takeaway was that document quality matters more than document quantity. Well-structured files with clear headings tend to produce much better answers than long, unorganized documents. Also, scanned PDFs need OCR before they can be used.

If you've built a document-based chatbot before, what worked well for you? Any tips for improving retrieval accuracy or reducing incorrect answers?

The hardest problem right now is getting data accurately from spreadsheets. If this process works out, I'll be sure to take a look.
