Format your SQL queries with proper indentation and uppercase keywords. Makes complex queries readable. Supports SELECT, INSERT, UPDATE, DELETE, and more. Runs entirely in your browser.
Readable SQL is maintainable SQL. Complex queries with multiple JOINs, subqueries, and WHERE conditions quickly become unreadable when written on one line. This formatter parses SQL and applies consistent indentation, keyword capitalization, and line breaks. It handles SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and most SQL dialects (MySQL, PostgreSQL, SQL Server, SQLite). Properly formatted SQL is easier to review in pull requests, debug when queries return unexpected results, and maintain when business requirements change. The tool runs entirely in your browser — your queries are never sent to any server, making it safe for sensitive production queries.
It handles standard SQL syntax used by MySQL, PostgreSQL, SQL Server, SQLite, and Oracle. Dialect-specific features (MySQL backticks, PostgreSQL arrays, T-SQL specific syntax) are generally preserved during formatting.
No — formatting only changes whitespace, line breaks, and optionally keyword casing. The logical SQL statement remains identical. It's purely cosmetic, like code formatting in any language.
Convention says yes — SELECT, FROM, WHERE, JOIN in uppercase improves readability by distinguishing keywords from table/column names. Most style guides recommend it. This formatter can uppercase keywords automatically.
Basic stored procedure formatting works — CREATE PROCEDURE, BEGIN/END blocks, IF/ELSE, and DECLARE statements. Very complex PL/SQL or T-SQL with advanced constructs may need manual adjustment after formatting.
Yes — all formatting happens in your browser using JavaScript. No data is transmitted to any server. You can verify this in your browser's Network tab. It's safe for production queries containing sensitive data.
