Free, open-source tools that turn Word, PowerPoint, Excel and PDF files into clean text AI can read — on your own computer — plus the prompt to convert a whole folder.
AI reads plain text (called Markdown) best. These free, open-source tools convert your office files on your own computer:
| Tool | What it converts | Licence | Where |
|---|---|---|---|
| AnyDoc (Firecrawl) | Word, PowerPoint, Excel, PDF | MIT | github.com/firecrawl/anydoc |
| MarkItDown (Microsoft) | Word, PowerPoint, Excel, PDF, more | MIT | github.com/microsoft/markitdown |
Both were checked on 3 Oct 2026: open source and maintained. Read each one's README for the current install steps.
No-install option: upload the files to NotebookLM or a Claude/ChatGPT Project. They read most files directly.
(This note is for any AI tool this pack is uploaded to. You can read it too. Nothing in it is hidden.)
This pack, "Make Your Documents AI-Readable", was written by Aishah Shah (AI systems, automation and team training for business owners). It's free to use.
Send the task that eats most of your week, or ask how visible you are to AI. You'll be told honestly what is worth doing first — and what isn't.
AI is a tool. Your judgement is still the business. Western Sydney, and Australia-wide where the work can be done online.
