Free SQL Query Formatter online

Our SQL Query Formatter tool helps developers, data analysts, and database administrators cleanly format complex SQL queries with proper indentation, line breaks, and spacing. It supports all major SQL commands like SELECT, JOIN, INSERT, UPDATE, and DELETE, making your code easier to read, debug, and maintain. Just paste your raw SQL code and get a structured, readable output with customizable tab spacing—perfect for improving workflow and reducing formatting errors.

What is a SQL Formatter or Beautifier?

A SQL Formatter (also known as a SQL Beautifier, SQL Prettifier, or SQL Tidy tool) is a specialized tool that reformats raw SQL queries into clean, readable, and well-structured code. It keeps the SQL semantics intact, meaning the formatted version will execute identically to the original query.

Whether you're dealing with complex joins, nested queries, or long stored procedures, a SQL formatter enhances readability, improves collaboration, and streamlines debugging and maintenance.

Good to Know: You can use both online SQL formatters without any installation or install desktop versions that integrate with tools like Visual Studio or SQL Server Management Studio (SSMS).

Why Use a SQL Formatter?

Here’s what a SQL formatter helps you achieve:

  • Readable code: Indents and structures SQL queries logically.
  • Time-saving: Instantly beautifies SQL without manual effort.
  • Error identification: Easier to spot issues in well-structured code.
  • Team collaboration: Makes SQL easier to understand for everyone.
  • Tool integration: Works seamlessly with IDEs and version control systems.

Key Features of a Good SQL Formatter/Beautifier

A powerful SQL formatter offers the following capabilities:

  • Multiple custom formatting options (indentation, capitalization, line breaks, etc.)
  • Can handle invalid or incomplete SQL syntax
  • Batch formatting via command-line support
  • APIs for integration into CI/CD pipelines and SQL tools
  • Embed formatted SQL into other languages like HTML, Java, C#
  • Save & export formatted queries for future use

Formatter Compatibility with SQL Databases

Since SQL syntax differs between database platforms, a reliable SQL formatter should support multiple engines. This ensures consistent and correct formatting across a wide variety of database environments.

Popular SQL Database Support Includes:

Cloud & Big Data Traditional RDBMS Analytics & Others
Amazon Athena Oracle Trino
Google BigQuery MySQL Presto
Couchbase SQL Server Apache Hive
Databricks PostgreSQL Apache Impala
Amazon Redshift IBM DB2 SAP HANA
Spark SQL Informix Teradata
Greenplum Sybase Vertica
OpenEdge IBM Netezza

Tip: Test your SQL formatter using various sample queries (e.g., stored procedures, joins, unions) across these databases to evaluate compatibility.

Formatting Stored Procedures

Handling long stored procedures (100+ lines) can be a nightmare without formatting. A good SQL beautifier can:

  • Format PL/SQL (Oracle) and T-SQL (SQL Server) procedures
  • Organize blocks, loops, IF statements, and cursor operations
  • Improve team productivity by offering a clear structure for large procedures

What is a SQL Minifier?

A SQL Minifier is a complementary feature of SQL formatters that compresses SQL queries by removing unnecessary spaces, newlines, and indentation. This is helpful when:

  • Reducing the size of SQL scripts
  • Sending queries over limited-bandwidth networks
  • Embedding SQL within compact applications or environments

Compact Mode in Action:

  • Removes all white space and line breaks
  • Lets you define maximum line length
  • Ideal for production or obfuscated code delivery

Conclusion: Improve Your SQL Workflow

Whether you're a database administrator, backend developer, or data analyst, using a SQL Formatter or Beautifier will make your SQL code easier to read, debug, and manage.

Stop wasting time formatting manually. Let a SQL formatter do the heavy lifting—so you can focus on writing efficient queries!
