Free MySQL SQL Formatter & Beautifier Online

MySQL SQL often combines familiar relational syntax with implementation details that are easy to disturb during cleanup. Backtick-quoted identifiers can contain reserved words and mixed case, date functions frequently contain interval expressions, and MySQL 8 adds CTEs and window functions to older query patterns. A formatter must distinguish identifier quotes from string quotes and preserve the exact expression boundaries around functions such as DATE_FORMAT, DATE_SUB, IFNULL, and JSON_EXTRACT.

This MySQL formatter emphasizes readable joins, aggregation, and pagination. SELECT lists are split at useful boundaries, nested subqueries keep their scope, and GROUP BY and HAVING clauses remain visibly connected to the aggregate query they qualify. Window functions are formatted with their PARTITION BY and ORDER BY definitions on separate lines when they become long. Backtick paths such as `orders`.`created_at` remain intact, while comments and semicolon-separated statements keep their original order.

Open this page when you need a clean MySQL query for a migration review, an ORM diagnostic, a stored routine, or a dashboard. The editor starts with a MySQL 8-style example containing backticks, CTEs, date arithmetic, and a ranking window. You can change keyword and line-break options, format the query, and use the output diff to review the exact changes before copying or downloading the result.

That makes the page useful for both handwritten and generated SQL. When a query contains several aliases with quoted names, nested date calculations, or a window over an aggregate alias, consistent line breaks help reviewers distinguish the database logic from the visual noise produced by an ORM or migration generator.

Use the result in a pull request, migration file, or support ticket without manually reindenting every nested expression. The formatter’s dialect-specific landing page also gives readers context about why a backtick, interval, or window clause is present.
