About SQL Formatter
Format and beautify SQL queries. Supports MySQL, PostgreSQL, SQL Server and more.
SQL Formatter takes a dense, single line query and rewrites it with consistent indentation, one clause per line and aligned keywords so complex statements become readable at a glance. It understands SELECT, JOIN variants, CTEs, window functions, CASE expressions, subqueries and UNION branches, and it keeps string literals, comments and database specific syntax untouched. Dialect switches cover MySQL, PostgreSQL, SQL Server, SQLite, Oracle and BigQuery, adjusting keyword casing, identifier quoting and comma placement to match the style each database expects. Paste hundreds of lines and the formatter still returns instantly, with a compact mode that preserves line counts for comparing versions. A second tab minifies the query again for shipping inside application code, and a copy button hands you the result without leaving the page.

Frequently Asked Questions
Which database dialects does the SQL Formatter support?
It ships with presets for MySQL, PostgreSQL, SQL Server, SQLite, Oracle, BigQuery and a generic standard mode. Each preset controls keyword casing, identifier quoting, comma placement and indentation width, so the output matches the conventions of the database you write for. If your team follows its own style guide, adjust the casing and indent options manually and the formatter applies them to every query you paste.
