How to Format SQL Online

Formatting messy or minified SQL queries is essential for readability and code review. Our online SQL formatter makes it easy:

Paste your SQL: Copy your raw, messy, or minified SQL query into the left-hand input box.
Customize Settings: Choose your preferred indentation (2 spaces, 4 spaces, or tabs) and keyword casing (uppercase or lowercase) from the toolbar.
Click Format: Hit the "Format SQL" button. The tool will instantly parse your code and generate a clean, standardized version in the right-hand box.
Copy output: Use the "Copy" button to grab your beautified SQL ready for your database editor or codebase.

Supported SQL Dialects

SQL syntax varies slightly between database engines. Our SQL beautifier is designed to handle the most common standards and dialect-specific features, ensuring your code breaks and indents correctly regardless of your stack.

MySQL & MariaDB Supports backticks for identifiers and specific function syntax.

PostgreSQL Handles strict quoting, custom types, and JSONB operators correctly.

SQL Server (T-SQL) Formats bracketed identifiers [] and T-SQL specific clauses.

Oracle (PL/SQL) Supports complex PL/SQL blocks and Oracle-specific keywords.

SQLite & Standard SQL Perfect for lightweight databases and ANSI SQL92/99 standards.

Why Use an Online SQL Formatter?

Writing SQL queries is often a quick, iterative process, leading to messy, unformatted code (sometimes on a single line). Using a pretty print SQL tool offers several advantages:

Improved Readability: Properly indented code with aligned `AND`/`OR` clauses makes complex logic easy to follow.
Easier Debugging: Syntax errors are easier to spot when your subqueries and joins are visually structured.
Standardization: Enforce a consistent style (e.g., UPPERCASE keywords) across your team's codebase.
Productivity: Don't waste time manually pressing space/tab. Let the tool handle the formatting instantly.

SQL Formatter vs Manual Formatting

Developers often debate whether to use an automated tool or format code manually. While manual formatting offers granular control, it falls short in efficiency compared to modern tools:

Feature	Manual Formatting	IDE Plugins	Online SQL Formatter
Speed	Slow, character by character	Fast (shortcut keys)	Instant (Zero Setup)
Availability	Anywhere	Specific machine only	Any Device / Browser
Consistency	Prone to human error	High (Config dependent)	Perfectly Standardized

While IDE plugins are great for your primary workstation, an online SQL formatter is the ultimate solution for quick debugging, code reviews, or working on shared machines where you can't install extensions.
