What SQL dialects does this formatter support?

This SQL formatter works with standard SQL syntax compatible with MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Oracle, and most other relational databases. It handles common SQL constructs including JOINs (INNER, LEFT, RIGHT, FULL), subqueries, CTEs (WITH clauses), window functions, and stored procedure syntax.

Does the formatter change my SQL logic?

No — the formatter only changes whitespace, indentation, and keyword casing. It never modifies table names, column names, values, operators, or query logic. Your SQL executes identically before and after formatting. The tool is purely cosmetic and safe to use on production queries.

What is SQL minification used for?

SQL minification removes all unnecessary whitespace, comments, and line breaks to produce the most compact version of a query. This is useful for logging queries in a single line, embedding SQL in configuration files, or reducing the size of SQL sent over network connections in applications.

Can I format SQL with multiple statements?

Yes — the formatter handles multiple SQL statements separated by semicolons. Each statement is formatted independently with proper indentation. This is useful when formatting migration files, stored procedures, or batch scripts containing multiple queries.

Is my SQL data safe when using this formatter?

Completely safe — all SQL formatting happens entirely in your browser using JavaScript. No SQL is ever sent to any server or stored anywhere. This means you can safely format queries containing sensitive table names, column names, or data values without any privacy risk.
