About SQL Formatter

SQL Formatter takes minified or hand-written SQL and outputs it with consistent keyword casing, indentation, and line breaks that make complex queries easy to read and review. It supports standard SQL as well as dialect-specific syntax for PostgreSQL, MySQL, SQLite, and others. Formatted SQL is easier to debug, document, and share with teammates.

Frequently Asked Questions

Is SQL Formatter free?

Yes, completely free. No signup, no account, no usage limits. Use it as much as you need.

Is my data secure?

All processing happens directly in your browser using JavaScript. Your data is never sent to any server, stored, or shared. It stays entirely on your device.

Does it support PostgreSQL-specific syntax like CTEs and window functions?

Yes. The formatter understands PostgreSQL syntax including CTEs (WITH clauses), window functions (OVER), RETURNING, and dollar-quoted strings.

Does formatting change how the SQL executes?

No. SQL is whitespace-insensitive (outside of string literals), so formatting changes only the visual presentation and never affects query behavior or performance.
