Frequently Asked Questions
What SQL dialects are supported?
Standard SQL, PostgreSQL, MySQL, MariaDB, SQL Server (MSSQL / Transact-SQL), SQLite, BigQuery, Redshift, Snowflake, Db2, PL/SQL (Oracle), and Spark SQL.
What formatting rules are applied?
Keywords UPPERCASED, consistent indentation (2 or 4 spaces), line breaks before major clauses (SELECT, FROM, WHERE, JOIN), and aligned operators.
Does it validate SQL syntax?
Non — formatting is cosmetic. It assumes input is valid SQL. Invalid SQL may produce unexpected output.
Can I format stored procedures?
Yes, and CTEs (WITH ... AS), window functions (OVER PARTITION BY), and JSON operators all format correctly.
Is my query sent to a server?
Non. We use the sql-formatter JavaScript library, running entirely in your browser. Safe for production queries with sensitive schema names.

Why Use SQL Formatter?
 
You should try SQL Formatter for a quick, private way to format and beautify sql queries. Processing happens in your browser and files are never uploaded; the few tools that need an outside service say so on the page.
 
On the other hand, dedicated APIs or desktop tools suit batch processing better. They also handle server-side automation. For everyday tasks, browser tools offer the best speed, privacy, and convenience.
