ChatGPT's Data Analyst Mode Is Free — and Underused

ChatGPT's 'Data Analyst' (formerly Code Interpreter) and Claude's analysis tool both let you upload spreadsheets and ask questions in plain English. They run real Python under the hood, so the output is reproducible — but you should always sanity-check the numbers and ask to see the code.

Some examples

• Upload your school's basketball stats CSV → 'plot points per game vs. minutes played, fit a regression line, and tell me the correlation.' Done in 30 seconds.
• Ask 'show me the Python code you used' to verify the analysis — paste it into a real Jupyter notebook later if you want to learn.
• The free tier of ChatGPT includes data analyst mode now (since late 2024); paid Claude has the same feature.
• For survey data, prompt: 'For each question, tell me mean, median, mode, and flag any that have <30 responses.' That's a one-line first pass.

Try it!

Find any free CSV dataset on data.gov or kaggle.com (try 'high school sports' or 'movies'). Upload to ChatGPT and ask 3 questions about it: a count, a chart, and a comparison between two groups. Save the answers and the code.
