What is SQL Formatter?

A SQL formatter takes a SQL query — often written on a single line or with inconsistent formatting — and restructures it with proper indentation, keyword capitalization, and line breaks to make it easy to read and understand.

Well-formatted SQL is essential for code reviews, debugging complex queries, documentation, and maintaining large SQL codebases. Most style guides recommend uppercase keywords (SELECT, FROM, WHERE), each major clause on its own line, and consistent indentation for sub-clauses.

This formatter handles SELECT queries, JOINs, WHERE clauses, GROUP BY, ORDER BY, subqueries, INSERT, UPDATE, DELETE statements, and common SQL keywords across all major databases (PostgreSQL, MySQL, SQL Server, SQLite, Oracle).

FAQ

Does this work with all SQL dialects?
Yes, the formatter handles standard SQL keywords used across PostgreSQL, MySQL, SQL Server, SQLite, and Oracle. Dialect-specific extensions are preserved as-is.
Does it validate my SQL?
No, this is a formatter, not a validator. It restructures the visual layout of your SQL without checking for syntax errors or semantic correctness.
Will it change my query logic?
No. The formatter only changes whitespace, indentation, and keyword capitalization. The logical meaning of your query is never modified.
