About SQL Prettify & Format

SQL Prettify & Format is a developer tool that transforms messy, compressed, or poorly formatted SQL queries into clean, readable code. SQL (Structured Query Language) is the backbone of database operations, and poorly formatted queries make debugging, maintenance, and collaboration extremely difficult. Our formatter automatically adds proper indentation, line breaks, keyword capitalization, and spacing to make SQL queries easy to understand at a glance. It supports all major SQL statements including SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, and complex JOIN operations.

How to Use SQL Prettify & Format

  1. Paste Your Query: Copy your messy, minified, or unformatted SQL query and paste it into the input textarea above.
  2. Select Keyword Style: Choose whether SQL keywords should be converted to UPPERCASE, lowercase, or left as-is based on your team's coding standards.
  3. Click Format: Press the "Format SQL" button to instantly beautify your query with proper indentation, line breaks, and spacing.
  4. Copy Result: Use the copy button to grab the formatted SQL for your editor, documentation, or code review.

Features

Keyword Capitalization Automatically capitalize or lowercase SQL keywords to match your coding style guide.
Smart Indentation Properly indent nested clauses, subqueries, JOIN conditions, and column lists.
JOIN Formatting Automatically format LEFT JOIN, RIGHT JOIN, INNER JOIN, and CROSS JOIN clauses with proper alignment.
All SQL Dialects Works with MySQL, PostgreSQL, SQL Server, Oracle, SQLite, and other SQL databases.
One-Click Copy Copy the formatted query to your clipboard instantly for use in editors and tools.
Browser-Based Processing All formatting happens in your browser - no data is sent to any server.

Benefits

Formatted SQL queries are dramatically easier to read, debug, and maintain. Studies show that developers spend 70% of their time reading code, making readability a critical factor in productivity. Our formatter enforces consistent formatting across your team, reduces merge conflicts from formatting changes, and makes code reviews more efficient. Clean SQL also helps identify performance issues like missing indexes or unnecessary joins that might be hidden in compressed queries.

Use Cases

Code Review Format SQL before code reviews to make queries easy to understand and approve.
Debugging Beautify complex queries to spot logic errors, missing conditions, and performance issues.
Documentation Format SQL examples for technical documentation, wikis, and training materials.
Migration Scripts Clean up SQL migration files for better version control history and team collaboration.

Why Use TooliFyra's SQL Formatter?

TooliFyra's SQL Formatter understands SQL syntax deeply. Unlike simple text formatters, it parses SQL structure to indent subqueries correctly, align JOIN conditions, and format WHERE clauses with proper logic. The keyword capitalization options let you enforce team standards automatically, and the browser-based processing ensures your database queries remain private.

Frequently Asked Questions

The formatter works with all SQL dialects including MySQL, PostgreSQL, SQL Server, Oracle, SQLite, MariaDB, and more. It handles standard SQL syntax and common extensions used across different database systems.
No, formatting only changes whitespace, line breaks, and keyword casing. The query logic and results remain exactly the same. SQL is case-insensitive for keywords, so capitalization changes don't affect execution.
Yes, the formatter handles CREATE PROCEDURE, BEGIN/END blocks, DECLARE statements, and control flow like IF/ELSE and WHILE loops. Complex stored procedures will be formatted with proper indentation.
Subqueries are automatically indented relative to their parent query. Nested subqueries get progressively deeper indentation, making the query hierarchy clear and easy to follow.
