NotebookLM can now read your Google Sheets and Drive PDFs

If you use NotebookLM regularly, you know the specific brand of annoyance that comes with downloading a file from Google Drive just to drag it right back into a Google browser tab.

That awkward middle step is finally going away.

Google rolled out a handy update to NotebookLM, allowing users to import PDFs and Google Sheets directly from Google Drive. You can now also copy and paste Drive file URLs directly into the source box, with Microsoft Word (.docx) support set to arrive soon.

Cutting out the busywork

The update solves one of the biggest friction points in day-to-day research workflows.

Instead of juggling duplicate files between your hard drive and the cloud, you can now connect Drive documents in just a few clicks. Pasting multiple URLs at once makes gathering references across folders almost instant.

Support for Google Sheets is especially useful. While raw text and PDFs have always played well with AI, spreadsheets often tripped up context windows. Now, NotebookLM can read Sheets files natively, helping you generate summaries from raw data and answer specific questions without breaking the table structure.

With Word documents on deck, the tool is checking off the last few file formats standing between users and a seamless workflow.

Growing into a serious research engine

NotebookLM has quietly become one of Google's most compelling AI experiments since launching late last year.

It first grabbed headlines with Audio Overviews, the viral feature that converts dense research papers into lifelike two-host podcasts. Since then, Google added Video Overviews to build visual slide presentations and launched dedicated mobile apps across Android and iOS.

Recent reporting also points to Google rolling out Deep Research capabilities, letting the assistant plan research tasks, browse the web autonomously, and bring back source-grounded briefings.

Pairing that kind of web-scale synthesis with your private cloud documents turns NotebookLM into a genuine research hub.

Why it matters

For anyone buried in research, this update makes an already indispensable tool significantly faster to use.

Students, analysts, and writers no longer have to spend time curating local files. You can point the tool at your existing Drive repositories and start generating summaries, study guides, and audio debriefs in minutes.

From a competitive standpoint, this is Google leaning hard into its biggest unfair advantage: the Google Workspace ecosystem. Rivals like OpenAI and Anthropic have powerful models, but they do not own the storage infrastructure where millions of people keep their daily work.

We think this is the right way to build AI utility. Glamorous model breakthroughs get the spotlight, but solving minor workflow annoyances is what actually cements daily habits.
