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?
No — 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?
No. We use the sql-formatter JavaScript library, running entirely in your browser. Safe for production queries with sensitive schema names.
