About SQL Formatter

Format SQL for readability.

The SQL formatter parses your query using a tokenizer that recognizes SQL keywords, identifiers, operators, string literals, numbers, and comments across multiple SQL dialects. The token stream is then analyzed for structural elements — SELECT clauses, FROM clauses, JOIN chains, WHERE conditions, GROUP BY lists, subqueries, and CTEs. Each structural element is placed on its own line with context-appropriate indentation, keywords are optionally uppercased, and consistent spacing is applied around operators and commas.

Use the left editor to enter your data. The output updates in real time. You can copy, clear, download, or expand either pane.

FAQs

What SQL dialects does the formatter support?
The SQL formatter supports standard SQL (ANSI) as well as dialect-specific syntax for MySQL, PostgreSQL, Microsoft SQL Server, Oracle, SQLite, and MariaDB. Dialect-specific keywords and functions are recognized and formatted correctly.
Does the formatter handle subqueries and CTEs?
Yes. Common Table Expressions (WITH clauses), inline subqueries, correlated subqueries, and derived tables are all formatted with proper indentation. Each CTE and subquery is indented to clearly show the query's logical structure.
Can I format stored procedures and multi-statement scripts?
The formatter handles multi-statement SQL scripts separated by semicolons. CREATE PROCEDURE, CREATE FUNCTION, BEGIN/END blocks, IF/ELSE statements, and DECLARE statements are indented according to their nesting level.
Does formatting change how my SQL query executes?
No. SQL formatting only adds whitespace, line breaks, and changes keyword casing. It does not alter the query logic, join order, or any execution plan. Your queries produce identical results before and after formatting.
Can the formatter uppercase SQL keywords?
Yes. You can choose to uppercase all SQL keywords (SELECT, FROM, WHERE, JOIN, etc.) while keeping table and column names in their original case. This is a widely adopted convention that improves SQL readability.
How does the formatter handle long SELECT lists?
Long SELECT lists are formatted with each column on its own line, aligned and indented under the SELECT keyword. This makes it easy to scan the selected columns and add or remove fields during query development.
