Format, beautify, and validate SQL queries with multiple dialect support.
SQL (Structured Query Language) is the standard language for managing and querying relational databases. It is used to insert, update, retrieve, and delete data in databases like MySQL, PostgreSQL, SQLite, and many others.
SQL queries are composed of statements and clauses that define what data to operate on. Common clauses include SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, and LIMIT.
This tool supports all major SQL dialects including MySQL/MariaDB, PostgreSQL, SQLite, Oracle, SQL Server (T-SQL), IBM Db2, and standard ANSI SQL. The formatter adapts to dialect-specific syntax such as PostgreSQL's :: type casts and SQL Server's square bracket quoting.
No. All formatting, minification, and validation happens entirely in your browser using JavaScript. Your SQL queries never leave your device.
Formatting adds proper indentation, line breaks, and consistent keyword casing to make SQL queries human-readable. Minification removes all unnecessary whitespace and compresses the query into a compact single line, which is useful for reducing query log size or embedding queries in application code.
Yes. The validator checks for basic syntax errors such as unmatched parentheses, missing semicolons, and invalid keyword placement. However, it cannot detect semantic errors like referencing non-existent tables or columns — that requires a full database engine.
Use the Keyword Case dropdown to select UPPER (keywords like SELECT), lower (select), or Keep to preserve the original casing. This setting is applied whenever you format or validate your SQL.
