What is ChatGPT Advanced Data Analysis?


This tool was formerly known as "Code Interpreter". Now, it comes with the brand new name "Advanced Data Analysis" but still many people do not know its power and capabilities. So continue reading ...

Where can I find ChatGPT Advanced Data Analysis?

How to analyze an Excel and generate graphs with ChatGPT


You can easily upload your excel file (e.g. expenditures) or any web analysis and let ChatGPT think about the possible ways to analyze it:


  • Upload your CSV or xls or even JSON
  • Ask ChatGPT how you can visualize it: "Which visualizations would you propose. Please create a graph as a PNG to download".
  • Then you could upload a PowerPoint template you usually need.
  • Ask ChatGPT to add the PNG into your PowerPoint.


What are the limitations of analyzing data with ChatGPT?



  1. ChatGPT's advanced data analysis cannot directly search the internet. If you attempt to, it will respond with something like: "I'm sorry, but I cannot directly browse the web or access external websites like Bing." To access the browsing feature, you must select it when initiating a "new chat". This means that if you wish to analyze data, you'll need to manually copy and paste the information from the co-browsing service to the advanced data analysis service. Admittedly, this can be a bit cumbersome.

  2. Remember, it's essential to avoid uploading confidential or personally identifiable information to ChatGPT Plus (find a simple guide about ChatGPT and policy and privacy). If you don't want OpenAI to potentially use this data for training their models or are uncertain about the implications, exercise caution. Tools exist that can extract personally identifiable information, such as organization names, using machine learning techniques like NER.

  3. Overall, you can discover patterns in data without being a data scientist or data mining specialist 🔍. However, there's a caveat: ChatGPT's Advanced Data Analysis doesn't always function perfectly. The quality of the analysis is directly related to the cleanliness of the data. It's crucial to critically evaluate the results from large language models like GPT. Those familiar with basic analysis methodology or data mining are better equipped to discern inaccurate responses from the model. If you're ever unsure, feel free to ask ChatGPT for clarity. Also, if you encounter issues with specific data formats, consider converting them (e.g., from csv to xls, or to json). You can even utilize ChatGPT to assist in cleaning your data.


With the ChatGPT Advanced Data Analyzer, you can create graphs, tables, ppts and more. It does not always work at first trial but give it a try😉.

What's RAG? The goal is for the language model is not to draw on its own knowledge (from the model), but for information to be enriched in the prompt. This is usually your own data you provide to the model (PDFs, systems).
