About TableView Data Tools

TableView Data Tools (tools.tableview.dev) is the data-processing wing of TableView.dev. Every viewer, converter, SQL console, and FinOps estimator runs entirely inside your browser tab powered by DuckDB-Wasm and SheetJS — no file you open is ever uploaded to a server.

Why client-side matters

CSV, Parquet, and Excel files frequently contain business data that should not leave a device. By executing analysis locally, TableView Data Tools eliminates the exfiltration, logging, and sub-processor risk inherent in server-side conversion SaaS.
