This is working in a live test.

Though it's been some time since this PR was submitted, I tested it and found that it still works well.

I added a test case and merged it into my fork to keep track of the functionality.

Working with this feature helped me see how Google Drive can serve as a simple general-purpose format converter — I appreciate the insight and your original contribution.

I use it in my gem 💎 undrive_google, which downloads the export formats of Google docs, including epub. 🥰

Thanks for the info! I took a quick look at undrive_google — it’s a neat concept, and I can see how supporting export formats like EPUB would be very useful.
The recent PR made me realize Google Drive could act as a lightweight document converter too. Appreciate the inspiration.😀
