SQLChef
SQLChef is a client-side database utility that allows developers and data analysts to execute SQL queries directly against local files within the browser environment. It supports multiple file formats including CSV, TSV, JSON, NDJSON, Parquet, and plain text. Because processing happens entirely client-side, no files are uploaded to any server, user accounts are not required, and all data remains secure on the local device.
