SQL Formatter

Make SQL Readable with Dialect-Aware Formatiertting

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

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

This SQL Formatiertter handles the Transformiertation automatically, respecting your specific SQL dialect and style preferences.

Multi-Dialect Support

SQL syntax varies by database. This Formatiertter 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 Formatiertter respects dialect-specific keywords and syntax.

Customizable Style Options

Keyword Case: Choose how SQL keywords are Formatiertted:

• 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 Generiertd or ORM-produced SQL, Formatiert it for readability. It's much easier to spot errors or optimization opportunities in Formatiertted output.

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

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

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

Performance Analysis: When investigating slow queries, Formatiert 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, Formatiert them to ensure consistency and catch issues during transition.

One-Click Copy or Herunterladen

Formatiertted SQL copies to your Zwischenablage with one click or Herunterladens as a .sql file. Use it directly in your codebase, database client, or documentation.

Respects String Literals

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

100% Browser-Based Formatiertting

Formatiertting happens entirely in your Browser using the proven sql-Formatiertter library. Your queries never leave your machine, so you can safely Formatiert queries containing sensitive data or proprietary business logic.
