SQL Formatter

Format and beautify SQL queries.

About SQL Formatter

The SQL Formatter transforms messy, single-line, or inconsistently formatted SQL queries into clean, readable, and properly indented code. Whether you're debugging a complex query, reviewing code, or preparing SQL for documentation, properly formatted queries are dramatically easier to understand and maintain. Paste any SQL statement – SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, or complex JOINs – and get instant, beautifully formatted output. The formatter intelligently places keywords on new lines, indents SELECT columns and subqueries, aligns conditions, and maintains proper spacing. Choose your indentation preference: 2 spaces (compact), 4 spaces (standard), or tabs. Enable uppercase keywords to follow the common SQL convention of UPPERCASE keywords with lowercase identifiers. The output preserves your query's logic while making the structure immediately apparent. This is invaluable when working with queries generated by ORMs, copied from logs, or inherited from other developers. All formatting happens locally in your browser – your queries are never sent to any server, making it safe for sensitive database operations.

Frequently Asked Questions

What SQL dialects are supported?

The formatter handles standard SQL syntax that works across MySQL, PostgreSQL, SQL Server, SQLite, and Oracle. Dialect-specific syntax is preserved.

Does it validate SQL?

No, this is purely a formatter. It structures the text but doesn't check for syntax errors or semantic correctness.

Why uppercase keywords?

It's a widespread convention: UPPERCASE for SQL keywords (SELECT, FROM) and lowercase for identifiers (table names, columns). It improves readability.

How are subqueries handled?

Subqueries are indented to show nesting level. Complex nested queries become much easier to follow with proper indentation.

Can I format multiple statements?

Yes, separate statements with semicolons. Each statement will be formatted independently with proper spacing between them.

Does it preserve comments?

Comments are preserved in place. Both -- line comments and /* block comments */ are maintained in the formatted output.

How do I handle long WHERE clauses?

The formatter puts each AND/OR condition on a new line, making long WHERE clauses readable and easy to verify.

What about stored procedures?

Basic procedure structure is formatted, but complex procedural logic (IF/LOOP) may need manual adjustment for optimal readability.

Why use 2 vs 4 spaces?

2 spaces keeps queries more compact on screen; 4 spaces provides clearer visual hierarchy. It's personal/team preference.
