Format SQL with dialect-aware pretty-printing for PostgreSQL, MySQL, SQLite, T-SQL, and PL/SQL. Custom indent, keyword casing, and uniform keyword break rules.
How to Use SQL Formatter in 3 Steps
Configure. Paste SQL into the input. The formatter auto-detects common patterns and runs regardless of trailing semicolons.
Process. Pick dialect (PostgreSQL, MySQL, SQLite, T-SQL, or PL/SQL), keyword case (UPPER/lower/Title), and indent size (2 or 4 spaces).
Export. Copy the formatted output. Strings and comments are preserved exactly; only whitespace and keyword casing change.

The 5 major ones: PostgreSQL, MySQL, SQLite, Microsoft T-SQL, and Oracle PL/SQL. Each has dialect-specific reserved keywords (e.g., PostgreSQL's RETURNING, MySQL's ENGINE).
Will it break my query?
No. The formatter only adjusts whitespace and keyword case. Strings, comments, identifiers, and the SQL logic itself are preserved exactly.
Is my SQL sent to a server?
No. Formatting runs in your browser. Your queries — which may contain PII, API keys, or proprietary schemas — never leave your device.
Is this tool free?
Yes. SQL Formatter on Pixlane is completely free with no signup required.
