Format SQL queries online with ToolTunnel's free SQL Formatter. Improve readability with consistent indentation, keyword casing, and support for popular SQL dialects. Format queries directly in your browser without uploading them to a server.
Unformatted SQL can be difficult to read, debug, and maintain. A SQL formatter organizes queries into a consistent structure, making joins, conditions, subqueries, and aggregate functions easier to understand.
Paste a query into the editor, choose your preferred formatting options, and format it instantly. Copy the result or download it as a SQL file.
SQL syntax varies between database engines. Choose the dialect that best matches your database so the formatter can apply the appropriate formatting rules.
Customize keyword casing and indentation to match your team's coding conventions. Use uppercase keywords for visibility, lowercase keywords for a compact style, or preserve their original casing.
Formatting improves readability but does not execute queries, change database records, or guarantee that a query is valid for your database.
A SQL formatter organizes SQL statements with consistent indentation, line breaks, and keyword casing to make queries easier to read and maintain.
The formatter supports Standard SQL, MySQL, MariaDB, PostgreSQL, SQLite, SQL Server T-SQL, Oracle PL/SQL, BigQuery, Snowflake, Redshift, Spark SQL, Trino, Db2, N1QL, and SingleStore.
Formatting is intended to improve presentation rather than query logic. Always review the formatted query before using it in production, especially when working with database-specific syntax.
Formatting is performed in your browser. The SQL Formatter component does not send your query to a formatting API.
Yes. Drag and drop a supported .sql or .txt file into the editor, then format the loaded query.
