Google’s NotebookLM tool is set to gain a new feature soon, allowing free users to import and analyze Google Sheets files directly into the platform. This update comes after recent back-end improvements aimed at boosting performance, quality, and contextual understanding.
Existing users can already access Google Sheets on NotebookLM’s paid tier, but free users have had to work around this limitation by converting sheets to supported formats like PDFs or Google Docs. The upcoming support for Google Sheets will make it easier for users to leverage data analysis without having to subscribe to the premium version of NotebookLM Plus.
