Paste your SQL query

Click Format

Hit the Format button. The tool adds proper indentation, capitalizes SQL keywords (SELECT, FROM, WHERE), and breaks long lines into readable blocks.

3

Adjust formatting options

Choose your preferred indent size (2 or 4 spaces), keyword case (uppercase or lowercase), and line break style. Toggle options to match your team's SQL style guide.

Frequently Asked Questions

Which SQL dialects are supported?
The formatter supports standard SQL, MySQL, PostgreSQL, SQLite, Microsoft SQL Server, and Oracle syntax. Most formatting rules apply universally across dialects.
Is my SQL data safe?
Yes. The formatter runs entirely in your browser using JavaScript. Your queries are never sent to any server — ideal for formatting queries containing sensitive table names or data.
Can it format complex queries with subqueries?
Yes. The formatter handles nested subqueries, CTEs (WITH clauses), CASE expressions, window functions, and multi-table JOINs. Each nesting level gets proper indentation.
