FAQ

Frequently asked questions

What is an SQL formatter?

An SQL formatter (also called an SQL beautifier) takes raw, unformatted, or messy SQL queries and reformats them with proper indentation, line breaks, and consistent keyword casing. This makes SQL much easier to read, debug, and maintain.

Is this SQL formatter really free?

Yes, completely free. There are no hidden charges, no usage limits, and no premium features locked behind a paywall. Use it as much as you need, whenever you need it.

Is my SQL data secure?

Absolutely. All SQL processing happens entirely in your browser using JavaScript. Your queries are never sent to any server, stored, or logged. This means sensitive database queries and schema information stay completely private.

What SQL dialects are supported?

Our formatter supports standard SQL syntax including MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), Oracle PL/SQL, and MariaDB. It handles most common SQL statements: SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, DROP, and more.

Can I customize the keyword casing?

Yes! You can choose between UPPERCASE (SELECT), lowercase (select), or Title Case (Select) for all SQL keywords. This lets you match your team's coding standards perfectly.

Does it handle complex queries?

Yes. The formatter handles subqueries, JOINs (INNER, LEFT, RIGHT, FULL, CROSS), Common Table Expressions (WITH/CTE), window functions (OVER, PARTITION BY, ROW_NUMBER), UNION/INTERSECT/EXCEPT, and nested statements of any depth.

Can I customize the indentation?

Yes! You can choose between 2-space or 4-space indentation using the dropdown in the toolbar.

Do I need to install anything?

No installation required. The SQL formatter works entirely in your web browser. Just open the page and start formatting. No downloads, no plugins, no setup.

Can I use this on my phone?

Yes, the tool is fully responsive and works on all devices — desktops, tablets, and smartphones. The interface adapts to your screen size for comfortable use anywhere.
