About this tool

This playground runs a full SQLite database engine (compiled to WebAssembly) inside your browser. Drop in one or more CSV files and each becomes a queryable table with automatically inferred column types — then use real SQL: joins across files, GROUP BY aggregations, window functions, CTEs, and more. Sample customers and orders tables are preloaded so you can experiment right away. Your data never leaves your device.

Your data stays private. All processing happens locally in your browser. No data is collected, stored, or sent to any server.
