About SQL Formatter

Format and beautify SQL queries with proper indentation, keyword capitalization, and consistent spacing. Supports SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and complex nested queries. All in your browser.

Keyword Formatting

Auto-capitalizes SQL keywords (SELECT, FROM, WHERE, JOIN). Configurable to uppercase or lowercase.

Smart Indentation

Nested queries, subqueries, and CTEs indented logically. Makes complex queries readable at a glance.

Multiple Dialects

Works with MySQL, PostgreSQL, SQLite, SQL Server, and standard SQL. Handles dialect-specific syntax.

Browser Privacy

SQL stays on your device. Formatting runs locally — no server upload, perfect for proprietary queries.

Run all team queries through the formatter to enforce consistent keyword casing and indentation across your codebase.
