Instantly format, beautify, and validate SQL queries. Supports MySQL, PostgreSQL, SQLite, SQL Server, Oracle & more — no signup needed.
A SQL formatter (also called a SQL beautifier) is an indispensable developer tool that automatically restructures raw SQL queries into clean, consistently indented, human-readable code. Whether you're debugging a complex multi-join statement in MySQL or reviewing a legacy stored procedure in SQL Server, formatting transforms tangled one-liners into well-organized blocks. Good SQL formatting follows established best practices: keywords in consistent case (SELECT, FROM, WHERE), each clause on its own line, and aliases clearly separated. For example, an unreadable select id,name from users where active=1 becomes a structured query with proper indentation and keyword capitalisation. This improves collaboration, reduces review time, and prevents costly syntax errors. Our free online SQL formatter supports MySQL, PostgreSQL, SQLite, Oracle, SQL Server (T-SQL), MariaDB, and BigQuery — covering virtually every modern database platform. Bookmark this SQL beautifier for daily development workflows.
A powerful, privacy-first SQL beautifier built for developers, DBAs, and data analysts.
Formats MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), Oracle, MariaDB, and BigQuery with dialect-aware keyword handling.
Format on-the-fly as you type or paste. Zero server round trips — all processing happens in your browser for maximum speed.
Color-coded output distinguishes keywords, strings, numbers, comments, table names, and operators at a glance.
Choose between 2-space, 4-space, or tab indentation to match your team's coding standards perfectly.
Auto-uppercase, lowercase, or preserve the original case of SQL keywords — your style, your choice.
Your SQL code never leaves your device. Everything runs client-side — perfect for sensitive database schemas.
Real-time syntax validation highlights issues and incomplete queries before you run them in production.
Upload .sql files directly, format them, and download the beautified result — ideal for large schema files.
Need to reduce whitespace? Toggle compact mode to minify SQL for use in scripts, configs, or API payloads.
No installation, no registration — just clean SQL in seconds.
Paste any raw SQL query into the input editor, or upload a .sql file directly from your device.
Select your SQL dialect, indentation style, keyword case preference, and enable syntax highlighting.
Hit "Format SQL" to beautify instantly. Copy to clipboard or download the formatted file.
Review the color-coded output, validate for errors, then use in your IDE, query editor, or docs.
Everything you need to know about our SQL formatter and beautifier.
A SQL formatter automatically reformats SQL queries by adding consistent indentation, line breaks, and keyword capitalisation. It makes complex queries readable, helps teams maintain coding standards, and reduces debugging time by exposing the logical structure of your SQL at a glance.
Our formatter supports Standard SQL (ANSI), MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), Oracle PL/SQL, MariaDB, and Google BigQuery. Switch dialects from the toolbar to apply dialect-specific keyword handling.
Absolutely. All SQL formatting happens entirely in your browser using JavaScript. Your code is never transmitted to any server, making this tool safe for sensitive or proprietary database schemas.
Yes! You can paste an entire SQL file containing multiple statements (separated by semicolons), and the formatter will process all of them correctly while maintaining proper separation.
SQL formatting (beautifying) adds whitespace, indentation, and line breaks to improve readability. SQL minification (compact mode) does the opposite — it removes all unnecessary whitespace to create the most compact form possible, useful for embedding SQL in application configs or API calls.
Yes, the formatter performs basic real-time syntax validation, detecting unclosed parentheses, missing semicolons, unbalanced quotes, and other common structural issues. For full execution validation, you'll need to run queries against your actual database.
