SQL Formatter

Beautify messy and minified SQL queries with proper formatting and syntax standards.

Why Format SQL?

SQL queries can quickly become complex, nested, and difficult to read—especially when they involve multiple JOINs, subqueries, or common table expressions (CTEs). Often, logs or ORMs will output SQL as a single minified string.

A SQL formatter takes that raw, dense text and beautifies it by adding consistent indentation, line breaks, and standardized capitalization for keywords. This drastically improves code readability, making it easier to debug logic errors and share queries with your team.

Supported SQL Dialects

Different database engines have slight variations in their syntax, reserved keywords, and functions. Selecting the correct dialect ensures the formatter accurately parses and styles your query. We support:

  • Standard SQL: The base ANSI SQL specification.
  • PostgreSQL: Supports Postgres-specific features like JSONB operators and RETURNING clauses.
  • MySQL / MariaDB: Handles backtick (`) quoting and specific built-in functions.
  • T-SQL: Microsoft SQL Server dialect, supporting variables (@) and specific procedural flow.
  • SQLite: Standard styling tailored for the lightweight SQLite engine.
