About SQL Formatting
SQL formatting transforms dense, hard-to-read queries into well-structured code with consistent indentation, keyword casing, and line breaks. This is essential for code reviews, debugging complex joins, and maintaining large query libraries.
This tool handles all major SQL statement types including SELECT with complex JOINs, subqueries, CTEs (Common Table Expressions), CASE WHEN blocks, INSERT/UPDATE/DELETE, and CREATE TABLE. It preserves comments and string literals while formatting.
A SQL formatter takes messy or minified SQL queries and reformats them with proper indentation, line breaks, and keyword casing. This makes complex queries much easier to read, debug, and maintain.
Is my SQL data safe when using this tool?▼
Yes, completely. This SQL formatter runs 100% in your browser using JavaScript. No SQL queries are ever sent to any server. Your data stays entirely on your machine.
What SQL dialects are supported?▼
The formatter supports Standard SQL, MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), and Oracle. Each dialect has specific keyword handling appropriate to that database system.
Does formatting change how SQL executes?▼
No, SQL formatting is purely cosmetic. Adding whitespace, newlines, and changing keyword case does not affect query execution or performance. The database engine ignores all formatting when parsing queries.
Does the formatter handle subqueries and CTEs?▼
Yes. The formatter correctly handles nested subqueries with proper indentation levels, Common Table Expressions (WITH/CTE clauses), CASE WHEN blocks, and complex JOIN conditions.
Can I customize the formatting style?▼
Yes. You can choose between 2 spaces, 4 spaces, or tab indentation. You can toggle uppercase keywords, control comma positioning (before or after columns), and toggle inline VALUES formatting.
