What is Csv Ai Analyzer?
CSV AI Analyzer is an open-source web application that analyzes CSV files using GPT AI and suggests charts or insights. The tool runs entirely locally in your browser with no backend, no file uploads, and no tracking, ensuring your data never leaves your machine. Users can drag and drop a CSV file, adjust parsing settings if needed, add their API key, and quickly receive analysis and visualizations.
Key features include automatic delimiter detection, encoding options, header selection, and a clean interactive data table view. The app supports multiple chart types including bar charts for comparison analysis, line charts for trend analysis, scatter plots, pie charts for distribution analysis, and area charts for cumulative data. The AI examines data for trends, proposes engaging visualizations, identifies irregularities, and provides quick insights without requiring manual formula writing.
The tool is built with a T3 stack consisting of Next.js, Tailwind v4, Recharts, and PapaParse, all written in TypeScript under an MIT license. Security is emphasized through strict secure cookies for storing API keys locally instead of localStorage. The application is self-hostable via Docker, allowing users to direct API requests to Ollama for completely local operation with no external API calls.
CSV AI Analyzer is ideal for data analysts, researchers, business professionals, and anyone who needs to quickly explore CSV files without spending time manually reviewing figures or determining suitable chart types. It is particularly beneficial when dealing with extensive or disorganized CSV files, or when users need a quick summary without the hassle of writing formulas or conducting manual assessments.
