Readable SQL is easier to review
The SQL formatter adds consistent indentation and line breaks to selects, joins, filters, subqueries and common DDL statements. Dialect selection helps preserve database-specific syntax.
The formatter does not run queries, inspect a database or guarantee semantic correctness. Review every query before executing it, especially destructive statements.
Frequently asked questions
Which SQL dialects are supported?
The tool supports standard SQL plus MySQL, PostgreSQL, SQLite, MariaDB, BigQuery, Transact-SQL and PL/SQL formatting.
Does it execute my SQL?
No. It only formats text and never connects to a database.
Can a formatter prove that a query is valid?
No. Formatting can expose obvious structure problems, but only your target database can fully validate its dialect and schema.
Is the query uploaded?
No. Formatting runs locally in your browser.
