QueryZy

QueryZy is a browser-based data analysis tool that lets you interact with your data files using natural language instead of complex query syntax. You simply upload CSV, JSON, Arrow, or Parquet files directly in your browser, then ask questions about your data in plain English. The AI-powered system translates your questions into SQL queries and returns instant results, making data analysis accessible even if you've never written a database query before.

What makes QueryZy stand out is its complete privacy focus — your data never leaves your computer thanks to DuckDB and WebAssembly processing everything locally in your browser. The tool automatically suggests relevant questions based on your data structure and generates visual charts from your results. You can then export cleaned, filtered, or aggregated data in various formats, making it perfect for quick data transformations and reporting.

This tool is ideal for non-technical professionals who need to work with data but don't want to learn SQL or set up complex software. Small business owners can use it to analyze sales data, marketers can cross-reference campaign results, and anyone with spreadsheet data can quickly filter, aggregate, and visualize information without waiting for IT support. It's particularly useful for one-time data cleaning tasks, quick reporting needs, and situations where data privacy is paramount.
