SQL Formatter

The formatter works with standard SQL syntax common to MySQL, PostgreSQL, SQLite, SQL Server, and others. It recognizes standard keywords like SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, and many more. Dialect-specific keywords may not be uppercased but the structure will still be formatted.

No. The formatter only changes whitespace and capitalization. It does not modify column names, table names, aliases, or any values. Your query logic remains exactly the same.

The formatter works with standard SQL syntax and handles most dialects including MySQL, PostgreSQL, SQLite, and SQL Server. It recognizes common keywords and formats them consistently, though dialect-specific syntax may not be specially formatted.

No. SQL formatting is purely cosmetic. The database engine parses the query identically regardless of whitespace, indentation, or keyword casing. Only the logical structure of the query matters for execution.

The tool applies a consistent style: keywords are uppercased, major clauses (SELECT, FROM, WHERE, JOIN, etc.) start on new lines, and subqueries are indented. For custom styles, consider using a dedicated SQL formatting library.

Well-formatted SQL is easier to read, debug, and maintain. It helps identify missing joins, incorrect conditions, and nested subqueries. In team environments, consistent formatting reduces code review friction and prevents errors.

Yes. The formatter handles nested subqueries, multiple JOINs, UNIONs, and complex WHERE clauses. Each major clause gets its own line, making even complex queries easy to read.
