Data Analyst — Custom GPT alternative

Data Analyst is an AI assistant that analyzes your data with real Python code and explains the results in plain language. Upload a spreadsheet or paste a table, ask a question in your own words, and get numbers you can trust, clear charts and a cleaned file back.

What it can do

• Reads CSV, Excel (XLSX), JSON and text tables, and tables pasted into the chat.
• Profiles your data: columns, types, missing values, duplicates and outliers.
• Cleans data: fixes formats and dates, removes duplicates, fills or flags gaps, merges files.
• Answers business questions: totals, averages, growth, top products, cohorts, seasonality.
• Builds charts: line, bar, scatter, histogram, heatmap and more, ready to paste into a report.
• Runs statistics: correlations, A/B test significance, regressions and simple forecasts.
• Creates pivot tables and delivers results as Excel or CSV files.
• Explains every finding in plain words, with the caveats that matter.

How to use it

• Sign in and attach your file, or paste a small table straight into the chat.
• Ask your question: "Which product grew fastest last quarter?"
• Ask for a chart, a cleaned file or a short summary for your manager.

Example requests

• Summarize this sales file and show the monthly trend
• Find duplicates and missing values in my data
• Is the difference between variant A and B statistically significant?
• Make a pivot table of revenue by region and month

Good to know

Calculations run in a secure Python sandbox, so the numbers come from your data, not from guesses. Files you attach stay in your chat history, and you can delete them at any time.
