SQL Formatter
Format and prettify SQL queries into clean, readable code for various dialects.
About SQL Formatter
The SQL Formatter standardizes your database queries into clean, professional code. It serves as a universal query beautifier, supporting multiple dialects like MySQL, Postgres SQL format, and Standard SQL to apply the correct syntax highlighting and indentation rules.
Enhance the maintainability of your database scripts. Complex queries with nested JOINs and subqueries can become unreadable over time. This database tool reorganizes them into a structured format, making code reviews and debugging significantly clearer.
Paste your SQL statement into the box. Select your target language (e.g., PostgreSQL). The tool will align keywords and clauses. You can copy the result directly into your DB management tool.
Under the Hood
SQL formatting utilizes the `sql-formatter` library, whichTokenizes the input string and applies dialect-specific rules (PostgreSQL, MySQL, Standard SQL) for indentation, capitalization, and newlines. The token stream handles complex nested queries, CTEs, and stored procedure syntax, ensuring that the semantic structure of the query drives the visual layout.
