Frequently Asked Questions

What does a SQL formatter do?

A SQL formatter takes messy or single-line SQL queries and restructures them with proper indentation, line breaks, and consistent keyword casing. This makes complex queries much easier to read, debug, and maintain.

Does this tool support all SQL dialects?

Yes, this formatter works with standard SQL syntax used by MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. It handles SELECT, INSERT, UPDATE, DELETE, JOINs, subqueries, CTEs, and window functions.

Will formatting change the meaning of my SQL?

No. SQL formatting only changes whitespace, line breaks, and letter casing of keywords. It never modifies table names, column names, values, or the logical structure of your query.

Is my SQL query sent to a server?

No. All formatting is done locally in your browser using JavaScript. Your SQL queries are never transmitted to any server, ensuring complete data privacy.
