SQL Formatter
Free online SQL formatter tool, minify supported
Why Format SQL Queries?
SQL queries written as single lines are hard to read and debug. Formatting adds proper indentation, line breaks, and consistent keyword casing. This makes complex JOINs, subqueries, and WHERE clauses much easier to understand. Formatted SQL is also easier to review in pull requests and documentation.
How to Format SQL
Paste your SQL query in the input area. Click Format SQL to beautify it with proper indentation and keyword highlighting. Click Minify SQL to compress it back to a single line. The tool supports SELECT, INSERT, UPDATE, DELETE, JOINs, subqueries, and common SQL syntax.
▶Which SQL dialects are supported?
The formatter handles standard SQL syntax common to MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. Dialect-specific features may not be perfectly formatted.
▶Does formatting change the query logic?
No. Formatting only changes whitespace, indentation, and keyword casing. The actual SQL logic and syntax remain identical.
▶Can I format stored procedures?
Basic stored procedure formatting is supported. Very complex procedural code with control flow statements may not format perfectly.
