Why should I format my SQL?

Formatted SQL is much easier to read, understand, and debug. Proper indentation and line breaks make the query structure clear, and capitalized keywords help distinguish SQL syntax from table/column names.

Which SQL dialects are supported?

This tool supports standard SQL as well as dialect-specific syntax for MySQL, PostgreSQL, SQL Server, Oracle, and SQLite. Select the appropriate dialect for best results.

Does formatting change how my SQL works?

No. SQL formatting only changes the visual presentation (indentation, spacing, keyword case). It does not alter the query logic or results in any way.

What is SQL minification?

SQL minification removes all unnecessary whitespace, comments, and line breaks, converting the query to a single compact line. This is useful for reducing query size in application code or logs.

Can I format stored procedures?

Yes. This tool can format stored procedures, functions, triggers, and other SQL blocks. The formatter handles BEGIN/END blocks, IF/ELSE statements, and loops with proper indentation.
