Free SQL Formatter & Beautifier 2026

Welcome to Code Formatters SQL Formatter – your go-to tool for organizing, beautifying, and standardizing database queries. Writing SQL often involves one-line queries from logs or messy legacy code that is impossible to read. Our online SQL beautifier instantly parses standard SQL (as well as variants like MySQL, PostgreSQL, T-SQL) and outputs clean, indented, and readable code.

Whether you are a database administrator debugging complex joins, a backend developer optimizing `SELECT` statements, or a data analyst creating reports, readability is key to preventing errors. A clear structure helps you verify logic, spot missing `WHERE` clauses, and ensure your joins are correct.

How to Use Our SQL Formatter

Clean up your queries in three simple steps:

Paste SQL: Copy your raw or minified SQL query into the "Input SQL" editor.
Select Dialect: (Optional) Choose your specific database language (MySQL, PostgreSQL, etc.) from the dropdown for better keyword highlighting.
Click Format: Hit the "FORMAT" button. The tool intelligently indents clauses like `SELECT`, `FROM`, `WHERE`, and `JOIN`.

Key Features

We use a robust parsing engine to ensure accuracy:

Multi-Dialect Support: accurately formats Standard SQL, MySQL, PostgreSQL, PL/SQL (Oracle), and T-SQL (SQL Server).
Smart Indentation: Aligns `AND`/`OR` conditions and nested queries for maximum readability.
Case Handling: Preserves your capitalization for table names while standardizing keywords (optional in future updates).
Privacy First: Your queries (which might contain sensitive table names) are processed locally in your browser. We never see your data.
Syntax Validation: If your SQL has a major syntax error that prevents formatting, the tool acts as a basic validator.

Why Format SQL?

1. Debugging Complex Queries

When a query spans 500 characters on a single line, finding a logic error is actionable. Formatting it into 20 structured lines makes the error obvious.

2. Code Reviews

Committing formatted SQL to your version control (Git) ensures your team can review the logic without struggling to parse the text.

3. Documentation

When documenting your database schema or stored procedures, clean SQL is essential for future maintainers.

Supported SQL Dialects

Standard SQL

The ANSI standard syntax used by many systems. Best for generic queries.

MySQL / MariaDB

Specific support for backtick (\`) quoting and MySQL-specific functions.

PostgreSQL

Handles standard double-quote (`"`) identifiers and Postgres-specific types.

T-SQL (SQL Server)

Support for bracket `[]` delimiters and `@variable` syntax used in Microsoft SQL Server.

Frequently Asked Questions

Does it execute the query?

No! This is purely a text formatter. It does not connect to any database and cannot execute or validate if tables exist.

Is it safe for sensitive data?

Yes. Processing happens in your browser via JavaScript. Your connection strings and query data never leave your computer.

Does it handle stored procedures?

Yes, it generally handles `CREATE PROCEDURE` and `BEGIN...END` blocks well, especially if you select the PL/SQL or T-SQL dialect.

Can I format multiple queries at once?

Yes. If your queries are separated by semicolons (`;`), the formatter will handle them as a script block.

Why did it uppercase my keywords?

Standard SQL convention is to use UPPERCASE for keywords (`SELECT`, `FROM`) and lowercase/mixed for table names. Our formatter defaults to this standard.

Does it support NoSQL?

No, this tool is for relational SQL databases. For JSON data (like MongoDB), better use our JSON Formatter.

Can I download the result?

Yes, simply click the Download icon to save your formatted query as a `.sql` file.
