SQL Formatter — Free Online Formatter

SQL formatting improves code readability by properly indenting and structuring queries. Our SQL Formatter supports multiple dialects including MySQL, PostgreSQL, SQLite, BigQuery, and Trino. Paste your SQL query into the input area, select your database dialect, and click Format to get properly indented, readable SQL. The formatter handles SELECT, INSERT, UPDATE, DELETE, JOIN, and all standard SQL statements. It also recognizes dialect-specific syntax like PostgreSQL's ILIKE, BigQuery's STRUCT types, and Trino's INTERVAL syntax for accurate and dialect-correct formatting. Formatted SQL is easier to debug, review, and maintain. The tool preserves your query logic while applying consistent formatting rules — proper keyword casing, line breaks for clauses, and indentation for nested subqueries. This is especially helpful when working with complex queries that have multiple JOINs, subqueries, or CTEs (Common Table Expressions). You can copy the formatted output with a single click for use in your database client, code editor, or version control system. All formatting happens locally — your queries are never sent anywhere. This makes it safe to use with sensitive database queries containing customer data, proprietary business logic, or confidential reporting logic and analytics.
