A SQL formatter (also called SQL beautifier or SQL pretty printer) is a tool that takes messy, unformatted SQL code and restructures it with proper indentation, line breaks, and keyword casing to make it readable and maintainable.
Formatted SQL is easier to read, debug, and maintain. Proper indentation reveals the logical structure of complex queries, consistent keyword casing improves scannability, and clean formatting helps teams collaborate on database code.
Our SQL formatter works with standard ANSI SQL and most common database dialects including MySQL, PostgreSQL, SQL Server (T-SQL), Oracle, SQLite, and MariaDB. The core formatting rules apply universally across dialects.
Convention varies by team and database. UPPERCASE keywords (SELECT, FROM, WHERE) are traditional and help distinguish SQL keywords from table/column names. Lowercase is more modern and easier to type. Choose what your team prefers and stay consistent.
2 or 4 spaces are most common. 4 spaces provides clearer visual hierarchy for complex nested queries. 2 spaces keeps code compact. Tabs work well if your team has varying preferences. Choose based on your coding standards.
The formatter adds line breaks before major clauses (SELECT, FROM, WHERE, JOIN, ORDER BY, etc.) and indents continuation lines. Subqueries and nested statements are indented to show their logical hierarchy.
Yes! All SQL formatting happens entirely in your browser using JavaScript. Your queries are never sent to any server, never logged, and never stored. This is crucial for formatting queries containing sensitive database schemas or data.
Yes, safely. Since formatting is 100% client-side, you can format queries containing table names, column names, or even test data without any privacy concerns. Nothing leaves your browser.
Paste your SQL query in the input box on the left, select your preferred indent size and keyword case, then click "Format SQL". The formatted result appears on the right - click "Copy" to copy it to your clipboard.
Yes! Our SQL formatter is 100% free with no limits, no signup, and no ads. Format as many queries as you need for development, debugging, or documentation.
Yes! The formatter handles multiple statements separated by semicolons. Each statement will be formatted with proper spacing between them.
The best SQL formatter is one that's fast, handles your SQL dialect, and respects your formatting preferences. Our online formatter works instantly in your browser, supports all major SQL dialects, and lets you customize indentation and keyword case.
Good SQL formatting includes: uppercase keywords (SELECT, FROM, WHERE), new lines before major clauses, consistent indentation for readability, and aligned columns in SELECT lists. Our formatter applies these rules automatically.
While VSCode has SQL formatting extensions, our online formatter is great for quick formatting without installing anything. Paste your query here, format it, and copy back to VSCode.
Yes! Paste your entire SQL script - including CREATE TABLE statements, stored procedures, or multiple queries - and our SQL beautifier will format everything with consistent styling.
Proper SQL formatting improves readability: each clause on its own line, indented subqueries, consistent keyword casing, and aligned columns. This makes code reviews easier and bugs more visible.
