Make SQL Readable with Dialect-Aware Formateting

SQL queries from ORMs, query builders, or Génèred code are often crammed into single lines or Formateted inconsistently. Trying to review SELECT * FROM users WHERE id = 1 AND status = 'active' AND Créed_at > '2024-01-01' ORDER BY name is painful. Properly Formateted SQL with appropriate line breaks and indentation is drastically easier to read and debug:

SELECT *
FROM users
WHERE
  id = 1
  AND status = 'active'
  AND Créed_at > '2024-01-01'
ORDER BY name

This SQL Formateter handles the Transformeation automatically, respecting your specific SQL dialect and style preferences.

Multi-Dialect Support

SQL syntax varies by database. This Formateter supports:

• Standard SQL: Generic, works with most databases
• PostgreSQL: With PostgreSQL-specific syntax
• MySQL & MariaDB: MySQL/MariaDB variants
• SQLite: SQLite dialect
• T-SQL: Microsoft SQL Server
• BigQuery: Google BigQuery SQL
• Hive & Spark: Data warehouse engines
• TiDB: Distributed SQL database

Select your database, and the Formateter respects dialect-specific keywords and syntax.

Customizable Style Options

Keyword Case: Choose how SQL keywords are Formateted:

• UPPERCASE: SELECT * FROM
• lowercase: select * from
• Preserve: Keep keywords as-is in the input

Indentation Size: 2 spaces (compact) or 4 spaces (readable), matching your team's SQL style guide.

Comma Position: Decide where commas appear in SELECT lists and WHERE clauses:

• Before: Place commas at the start of each new line
• After: Place commas at the end of each line (traditional)

Common SQL Development Workflows

Code Review: Before reviewing Génèred or ORM-produced SQL, Formate it for readability. It's much easier to spot errors or optimization opportunities in Formateted output.

Query Debugging: When a complex query isn't returning expected results, Formate it to understand the structure, identify logical issues, and verify WHERE clauses and joins.

Documentation & Examples: Formate SQL queries before including them in documentation, README files, or tutorials. Well-Formateted examples are easier for others to understand and modify.

Style Consistency: Enforce consistent SQL Formateting across your team by using this tool as a Formateter before committing queries to version control.

Performance Analysis: When investigating slow queries, Formate them first. Well-structured SQL is easier to analyze for missing indexes, unnecessary joins, or inefficient subqueries.

SQL Migration & Refactoring: When moving queries between systems or refactoring large SQL files, Formate them to ensure consistency and catch issues during transition.

One-Click Copy or Télécharger

Formateted SQL copies to your presse-papiers with one click or téléchargers as a .sql file. Use it directly in your codebase, database client, or documentation.

Respects String Literals

The Formateter is intelligent about string content—it won't break or reFormate text inside quoted strings, ensuring your SQL data remains intact and correct.

100% Navigateur-Based Formateting

Formateting happens entirely in your navigateur using the proven sql-Formateter library. Your queries never leave your machine, so you can safely Formate queries containing sensitive data or proprietary business logic.
