SQLified

SQLified is a browser-based tool designed to convert large CSV and TSV files into clean, ready-to-run SQL scripts. It addresses the challenge of preparing massive, real-world data files for import into databases by generating both CREATE TABLE and INSERT statements tailored for Postgres, MySQL, SQL Server, and SQLite. The platform is built specifically to handle big data loads, supporting files with millions of rows in a single pass.

Key features include smart type inference, which automatically detects data types such as INTEGER, BIGINT, NUMERIC, DATE/TIMESTAMP, BOOLEAN, and TEXT from the input data. Users have full control over the resulting schema, with the ability to override inferred types, rename columns, set primary keys, and adjust nullability settings. The output is designed to be immediately importable, minimizing surprises during the loading process by ensuring correct types and quoting for each supported SQL dialect.

All file processing occurs locally in the user's browser, with no data uploaded, stored, or retained by SQLified. This privacy-focused approach ensures that sensitive data remains on the user's device throughout the conversion process. No sign-up is required to try the tool, making it accessible for immediate use.

SQLified is intended for individuals who regularly manage large-scale data migrations or imports, such as database professionals and those who work with big data on a schedule. By focusing on speed, accuracy, and privacy, it streamlines the conversion of complex delimited files into SQL scripts suitable for major relational database systems.
