Free Online SQL Formatter & Beautifier

What is SQL Formatter?

SQL Formatter takes messy, hard-to-read SQL queries and transforms them into clean, properly indented code. Whether you inherited a one-line query from a coworker or need to clean up auto-generated SQL, this tool organizes your code with proper line breaks, indentation, and keyword formatting.

Why Would You Need to Format SQL?

Here are common situations where SQL formatting helps:

• Debug complex queries: A properly formatted query makes it much easier to spot missing clauses, wrong joins, or logic errors.
• Code reviews: Clean SQL is easier for teammates to review and understand quickly.
• Documentation: Formatted queries look professional in documentation, wikis, and README files.
• Learning SQL: Seeing the structure clearly helps beginners understand how queries are built.
• Comparing queries: When both queries are formatted the same way, differences become obvious.

How to Format SQL - Step by Step

1. Paste your SQL: Copy your messy SQL query and paste it into the input box.
2. Choose your options: Select whether to uppercase keywords (recommended) and pick your preferred indent size.
3. Click Format SQL: Your query is instantly reformatted with proper structure.
4. Copy the result: Click the Copy button to copy your formatted SQL to the clipboard.

How to Minify SQL - Step by Step

1. Switch to Minify mode: Click the "Minify / Compress" tab.
2. Paste your SQL: Enter the SQL you want to compress.
3. Click Minify SQL: Comments and extra whitespace are removed, creating a single-line query.
4. Copy the result: Use the minified version in your code or configuration files.

Frequently Asked Questions

Will formatting change what my query does?

No. Formatting only changes whitespace and letter case. The query logic remains exactly the same and will return identical results.

What SQL dialects are supported?

This formatter works with standard SQL and is compatible with MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. Dialect-specific features are preserved.

Is my SQL query stored or logged?

No. Your SQL is processed entirely in your browser session and is never stored, logged, or transmitted anywhere. Your queries remain private.

Can I format multiple queries at once?

Yes! Separate your queries with semicolons and they will each be formatted with proper spacing between them.
