What is SQL Formatter?

SQL formatting transforms unreadable single-line queries into indented, keyword-capitalized, human-readable SQL. Essential for code reviews, documentation, debugging ORM-generated queries, and learning SQL structure.

Supports PostgreSQL, MySQL, SQL Server, and standard ANSI SQL dialects.

Examples

Format a nested query

Paste any SQL — the formatter detects dialect and applies consistent style.

Output

Formatted multi-line SQL with proper indentation

Common Mistakes

Formatting SQL with vendor-specific syntax using wrong dialect
Assuming formatted SQL changes query execution plan — formatting is cosmetic only
Not formatting before pasting queries into documentation
Mixing tabs and spaces in manually edited formatted SQL
