About This Tool

Reading and reviewing complex SQL queries is much easier when the code is properly indented and consistently formatted. This tool reformats SQL statements by placing each major clause (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, etc.) on its own line, adding consistent indentation, and optionally normalizing keyword casing. All formatting happens entirely in your browser — your query is never sent to any server, making it safe for proprietary or sensitive database schemas.

Frequently Asked Questions

Does this support all SQL dialects (MySQL, PostgreSQL, SQL Server, etc.)?

The formatter handles standard ANSI SQL keywords that are common across MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. Dialect-specific functions and syntax are passed through unchanged, so your queries stay valid regardless of dialect.

Is my SQL query sent to a server?

No. All formatting logic runs entirely in your browser using JavaScript. No data is transmitted anywhere, making this tool safe for confidential queries, internal schema names, and sensitive data.

What is comma-first style?

Comma-first (or leading-comma) style places the comma at the beginning of each new column line rather than the end of the previous one: , column_name. Some teams prefer this because it makes it easier to spot missing or extra commas during code review.
