How to Chat With Word, Excel, and PowerPoint Files Using AI: A Step-by-Step Guide

To chat with Office files — Word documents, Excel spreadsheets, PowerPoint decks — a tool reads the file's content and lets you ask about it in plain language: “What's the conclusion in this report?” or “Which slide covers Q3 revenue?” — instead of you scrolling through pages, rows, or slides looking for one number. The answer comes back grounded in the file's actual content, with a pointer back to where it found it.

Under the hood it works the same way as chatting with a PDF: the file is converted to text, split into chunks, each chunk is embedded, and your question retrieves the most relevant ones before a language model writes an answer from them. We cover the general mechanism in our RAG explainer; for Office files the extra step is converting the original format into plain text first.

1. Pick a tool that accepts Office formats directly, not just PDFs.
2. Upload the .docx, .xlsx, or .pptx file and wait a few seconds while it's converted and indexed.
3. Ask a broad question first, like “Summarize this document” or “What's on each slide?”
4. Follow up with specific questions — a figure from a spreadsheet, a bullet point from a slide, a clause from a contract.
5. Add related files to the same project to ask questions that span all of them at once.

Converting a spreadsheet or slide deck to plain text necessarily flattens the layout — the chat only needs the words, not the visual design. Tables generally convert cleanly enough that rows and columns stay associated with each other. A detail worth knowing: images embedded inside a PowerPoint slide can also be captioned by AI during indexing, so a chart or photo on a slide becomes searchable text too, not just the slide's bullet points.

Office files rarely live in isolation — a project report might sit next to a PDF appendix, a web page with the public announcement, or a recorded walkthrough. Keeping them in one project means a single question can pull from the slide deck, the spreadsheet, and the surrounding context together, instead of you manually cross-referencing each file — see how to chat with a website for the web-page side of that workflow.

Doxy lets you chat with Word, Excel, and PowerPoint files the same way you'd chat with a PDF: upload the file, wait for it to index, and start asking. It's all part of the same AI document chat and document Q&A workflow, so spreadsheets, decks, reports, and every other source in a project stay searchable together with citations back to the original file.
