SQL Formatter

How to use

• Choose your SQL dialect, indentation style, and keyword casing from the dropdowns.
• Paste a raw or minified SQL query into the text area, then press Format SQL.
• Press Minify to collapse the query into a single compact line for use in code or configs.
• Use Load Sample to explore the tool with a multi-table JOIN query before pasting your own.

What this is for

SQL Formatter turns dense, unreadable queries into properly indented, syntax-highlighted SQL so you can audit joins, debug conditions, and review logic at a glance. It supports Standard SQL, MySQL, PostgreSQL, SQLite, and SQL Server dialects, and lets you normalize keyword casing for team style guides. The minifier strips whitespace and comments to produce lean query strings for embedding in application code. All processing runs in your browser.
