QueryZy

QueryZy is a browser-based tool for analyzing data files. Users import CSV, JSON, ARROW, or PARQUET files by drag and drop or by pasting URLs, then ask questions in natural language. The page states that QueryZy generates the SQL, plots results on charts, and exports resulting data tables and charts. The page says files stay on the user's computer, that the tool uses DuckDB and WebAssembly, and that it supports large datasets. A 7-day free trial is offered, and a refund can be requested within 7 days of purchase.
