- Save the exported file, ensuring the data has clean headers and consistent formatting for better analysis.
- Upload the Exported File to NotebookLM
- Open your browser and go to Google NotebookLM.
- Log into your Google account.
- Click New notebook.
- Choose Upload File and select your exported PDF or TXT file.
- Click Open to upload.
- Interact with Your Spreadsheet Data in NotebookLM
- NotebookLM will quickly scan and digest your uploaded file.
- It automatically generates summaries and key insights.
- You can now ask natural language questions about your spreadsheet data, such as identifying trends, calculating summaries, or extracting specific information.
- You can also request creative thoughts or summaries based on your data.
- Review and Use Notes
- NotebookLM provides source-grounded answers with citations back to your uploaded file.
- Use the summarizations and interactive Q&A to gain insights that would normally require manual Excel analysis.
Harnessing NotebookLM's Features
NotebookLM offers additional features such as audio overviews and mind maps.
- To create a customized audio summary, prompt NotebookLM with: "Provide an audio overview summarizing key trends from this quarterly data".
- NotebookLM generates a summary and suggests relevant questions for analysis.
- To generate a mind map summarizing relationships and insights into the quarterly sales data, prompt the system with: "Generate a mind map summarizing relationships and insights into the quarterly sales data".
- The mind map visually highlights connections between products, regions, performance metrics, and customer satisfaction, allowing for easy interpretation and communication of complex information.
Leveraging NotebookLM for Decision-Making
NotebookLM's insights can guide decision-making, such as reviewing pricing strategies or supply chain efficiencies based on growing sales but shrinking profit margins for a product. One example of a natural language query using NotebookLM to identify high-performing regions or products is: "Which region had the highest sales in Q2?"
The average customer satisfaction score, as calculated by NotebookLM, is 86.25%. To improve overall customer satisfaction, consider applying customer service practices from high-performing regions to low-performing regions.
In summary, the key is to export your Excel spreadsheet into a supported format, upload it to NotebookLM, then use natural language queries to analyze and summarize your data interactively. This workflow leverages NotebookLM’s NLP strengths despite it not natively supporting Excel files, by using PDF/TXT exports as an intermediate format for analysis.
