AI Data Analyst Chatbot vs ExcelGPT

AI Data Analyst Chatbot is free, MIT-licensed software for self-hosted web use. It lets analysts and data practitioners explore structured datasets by asking questions in plain English, without SQL or extensive coding knowledge. Users upload CSV or Excel (XLSX) files, which are processed during the session and not permanently stored. Automated profiling covers columns, distributions, summary statistics, missing values, duplicates, and data-quality issues. Statistical analysis can surface variation, outliers, correlations, and patterns, and suggest statistical tests. Interactive visualizations accompany explanations and statistical insights. The project lists Streamlit, pandas, NumPy, SciPy, Plotly, LangChain, and Groq LLM (LLaMA 3.1). Running the app requires a Groq API key in the GROQ_API_KEY environment variable; the README directs users to install dependencies and launch Streamlit at localhost:8501. There are no SQL connections or team-collaboration features. Contributions are invited through forks, pull requests, or issues.

ExcelGPT turns plain-language spreadsheet questions into formulas, charts, cleaned data, templates, and analysis workflows. Its formula generator supports more than 400 functions across Excel, Google Sheets, WPS, and LibreOffice Calc. Users can upload spreadsheets and chat across multiple files and sheets to clean, merge, or query data, while Work Agent runs multi-step workflows across files. ChatDB connects to MySQL, PostgreSQL, Supabase, and SQL Server, restricting database work to read-only SELECT queries through a query guard and read-only transaction. Imports include Excel, CSV, ODS, PDF, PNG, and JPG files, with XLSX as an export format. Google Sheets connection is optional and uses per-file OAuth permission; ExcelGPT says it cannot browse or read other Google Drive files. ChatGPT with GPT-4o/GPT-5 is available, alongside Claude, Gemini, and OpenAI workflows. The free plan offers up to 90 credits per month through daily check-in. Pro costs $19.90 a month, and Max costs $29.90 a month. ChatGPT-powered features need a live connection, though the last response is cached for offline reading.
