Frequently Asked Questions
What is SQL formatting and why should I format my SQL queries?
SQL formatting restructures your code with consistent indentation, line breaks after major keywords, and proper keyword casing. Well-formatted SQL is significantly easier to debug, review in pull requests, and maintain over time. Most SQL style guides recommend uppercase keywords like SELECT, FROM, WHERE and consistent indentation for JOIN clauses, subqueries, and CASE expressions. This tool handles all of that automatically.
Does this SQL formatter support different database dialects?
This formatter handles standard SQL keywords shared across MySQL, PostgreSQL, SQL Server, Oracle, and SQLite. It recognizes major clauses including SELECT, FROM, WHERE, JOIN variants (INNER, LEFT, RIGHT, FULL, CROSS), GROUP BY, ORDER BY, HAVING, UNION, INSERT INTO, UPDATE, DELETE FROM, CREATE TABLE, ALTER TABLE, and more. Dialect-specific functions and syntax are preserved as-is during formatting.
Is it safe to paste production SQL queries into an online formatter?
Yes. This tool runs entirely in your browser using client-side JavaScript. Your SQL queries never leave your machine — nothing is sent to a server, stored, or logged. You can disconnect from the internet and the formatter continues to work. This makes it safe for formatting queries containing sensitive table names, column names, or data values.
